AngularJS / PHP / Javascript - I can not update the value of ng-model

First good evening. I have a simple table that is fed by a SQL database. I developed a button that aims to update the contents of the "ng-model" according to what you type in a simple form. The table is updated through an http.post request. The problem is that ng-models are not updating after burning, thus keeping the old values. Guys, I think it's some simple slide of mine with respect to passing parameters ... can you give me some strength?

<!-- BUTTON EDITAR -->

        <button ng-class="['uk-button', 'uk-button-primary', 'uk-button-small']" href="#modal-editar{{x.id}}" ng-click="updateRegister(x.id,x.cliente,x.descricao,x.valor,x.dataM,x.tipo)" uk-toggle>Update</button>

        <!-- INICIO MODAL EDITAR -->

        <div id="modal-editar{{x.id}}" uk-modal>
        <!-- BOTÃO DE FECHAR -->
            <div ng-class="['uk-modal-dialog']">

            <!-- TITULO DA ENTRADA -->
