How to Filter with two conditions using Modal in Ionic

I created a modal that filters only the categories that are registered, now I would like to get the selected items in the CheckBox of this modal and filter according to the categories selected by the user, I am not sure how to do this filter:

My modal:

    <ion-modal-view>
  <ion-header-bar>
    <h1 class="title">Escolha as Categorias</h1>
  </ion-header-bar>
  <ion-content>

        <div class="button-bar">    
            <button class="button button-stable button-block  icon-left ion-android-funnel" ng-click="save()">Aplicar Filtro</button>
        </div>

    <ion-list>
      <ion-checkbox ng-repeat="item in ofertass | unique:'categoria_comida_nome'" ng-model="checkItems[item.categoria_comida_nome]" ng-change="print()">{{item.categoria_comida_nome}}</ion-checkbox>
    </ion-list>

    <div class="button-bar">    
        <button class="button button-stable button-block  icon-left ion-android-funnel" ng-click="save()">Aplicar Filtro</button>
    </div>


  </ion-content>
</ion-modal-view>

My View where I call the modal:

<ion-view view-title="Promoções" hide-nav-bar="false" >
    <!-- content -->

    <!-- BOTÃO CARRINHO DE COMPRAS -->
        <ion-nav-buttons side="right"   >           
                <a  href="#/nhaac/carrinho" class="button button-icon icon ion-android-cart" > {{total}} </a>               
        </ion-nav-buttons>

    <ion-content delegate-handle="top" lazy-scroll  id="page-promocoes" class="has-header page-promocoes">

        <div class="button-bar">      

                 <!-- FILTRA POR... -->
                 <button class="button button-stable button-block  icon-left ion-android-funnel" ng-click="openModal()">
                     Filtrar           
                 </button>               


                <!-- ORDENA POR -->
                <button class="button button-stable button-block  icon-left ion-android-restaurant" modal-select="" ng-model="someModel" options="selectableNames" option-property="role" modal-title="Ordenar por...">Ordenar
                <div class="option">
                      <h1>{{option.name}}</h1>
                </div>
               </button>              

        </div>

        <div class="list animate-fade-slide-in-right">

            <div class="card" ng-repeat="item in ofertass | orderBy:someModel or " ng-init="$last ? fireEvent() : null" href="#/nhaac/ofertas_singles/{{item.cadastra_oferta_cod_oferta}}" >                    

                <div class="item item-thumbnail-top item-text-wrap">
                    <img class="imagemCapa" image-lazy-loader="lines" image-lazy-src="{{item.cadastra_oferta_foto}}"/>
                    <div class="promocao"><b>{{item.cadastra_oferta_desconto}}% OFF</b></div>
                    <div class="desconto"><b>Apenas: R$ {{item.cadastra_oferta_valor_com_desconto}}</b></div>

                    <div class="item"><h2><b>{{item.cadastra_oferta_titulo_promocao}}</b></h2></div>

                    <div class="item">
                        <h3>Categoria: {{item.categoria_comida_nome}}</h3>
                        <h3>
                            Preço Normal: <s><small class="preco">R$ {{item.cadastra_oferta_valor_sem_desconto}}</small></s><br>

                        <div class="to_trusted" ng-bind-html="item.cadastra_oferta_descricao"></div>
                    </div>    
            </div>

                <div>
                    <center><p style="position:relative;right:10px;bottom:0px;top:1px">

                    </p></center>
                </div>


                <a class="item button button-clear button-dark ink" href="#nhaac/ofertas_singles/{{item.cadastra_oferta_cod_oferta}}">MAIS INFORMAÇÕES</a>
            </div>

        <ion-list class="list">
        <ion-infinite-scroll ng-if="!noMoreItemsAvailable" on-infinite="onInfinite()" distance="5px" ng-if="hasMoreData"></ion-infinite-scroll>
        </ion-list>

        <ion-list class="list">
            <div class="item" ng-if="results.length == 0" >
                <p>Nenhum resultado encontrado...</p>
            </div>
        </ion-list>


        <ion-infinite-scroll ng-if="!noMoreItemsAvailable" on-infinite="loadMore()" distance="10%">
        <ion-infinite-scroll-content loadingSpinner="bubbles">
    </ion-infinite-scroll>



    </ion-content>
    <!-- ./content -->
</ion-view>

I wanted to add the category filter together with the sort filter that already exists:

<div class="card" ng-repeat="item in ofertass | orderBy:someModel or " ng-init="$last ? fireEvent() : null" href="#/nhaac/ofertas_singles/{{item.cadastra_oferta_cod_oferta}}" >    

To end this is the controller with the modal:

 .controller("promocoesCtrl", function($scope,$rootScope,$state,$ionicScrollDelegate,$http,$httpParamSerializer,$stateParams,$timeout,$ionicLoading,$ionicPopup,$ionicPopover,$ionicSlideBoxDelegate,$ionicHistory,ionicMaterialInk,ionicMaterialMotion,$ionicModal, sharedCartService,sharedFilterService){

    //put cart after menu
    var cart = sharedCartService.cart;

    // ORDENA POR...
    $scope.selectableNames =  [
    {name : "Por preço: Do Menor para o Maior", role : "+cadastra_oferta_valor_com_desconto"}, 
    { name : "Por preço: Do Maior para o Menor", role : "-cadastra_oferta_valor_com_desconto"},    
  ];


    $scope.getOpt = function(option){     
        return option.name + ":" + option.role;          
    };  
    // FIM DE ORDENA POR


    // PEGA OS ITENS SELECIONADOS NA MODAL E COLOCA NUM ARRAY
    $scope.checkItems = { };

    $scope.print = function() {
        console.log($scope.checkItems);
    }

    $scope.save = function() {
        var array = [];
        for(i in $scope.checkItems) {
            console.log($scope.checkItems[i]);
            if($scope.checkItems[i] == true) {
                array.push(i);
            }
        }
        console.log(array);
    }


    // INICIA FILTRO POR CATEGORIA    
      $ionicModal.fromTemplateUrl('/templates/filters/side-filter.html', {
        scope: $scope,

      $scope.$on('modal.hidden', function() {
        // Execute action
      });
      // Execute action on remove modal
      $scope.$on('modal.removed', function() {
        // Execute action
      });
    // FIM FILTRO POR CATEGORIA

How to put this array in the existing filter and have two conditions?

I do not know if it was clear, but I have this difficulty.

For these filters I'm using the Angular Filter: link
