How to pass a controller variable to the service?

I have a question, how do I step into a service a controller variable?

I have a screen that has a table, when the user clicks on a row of this table, it goes to another screen with the data filled in inputs. I have searched the internet, and I saw some people suggesting to record this variable in a service, to be able to call in another controller, but I could not make it work:

Controller:

(function() {
'use strict';

class PesquisaAtivosController {
  constructor($state, $scope, testeService){
    this.$state = $state;
    this.testeService = testeService;
  }

  teste(){
    var ItemSelecionado = document.getElementById('teste');
    console.log(teste);
    var _this = this;
    _this.$state.go("home.boletoEstoque2");
  }
}

PesquisaAtivosController.$$ngIsClass = true;
PesquisaAtivosController.$inject = ['$state','testeService'];

angular.module('app')
  .controller('PesquisaAtivosController', PesquisaAtivosController);})();

Page you should receive the data:

Template: just created a button with the function to appear this variable in the console

controller:

(function () {
'use strict';

class BoletoEstoqueController {
constructor($state, $scope, testeService) {
  this.$state = $state;
  this.$scope = $scope;
  this.testeService = testeService;
}

teste(){
  testeService.getItem();
  console.log(ItemSelecionado );
}

}

BoletoEstoqueController.$$ngIsClass = true;
BoletoEstoqueController.$inject = ['$state', 'testeService'];

angular.module('app')
  .controller('BoletoEstoqueController', BoletoEstoqueController);
})();

Service:

(function () {
'use strict';

function testeService($http, $q) {

    var ItemSelecionado = document.getElementById('teste');

    return {
        getItem: function () {
            return ItemSelecionado;
        },
        setItem: function(value) {
            ItemSelecionado = value;
        }
    };

}

testeService.$inject = ['$http', '$q'];

angular.module('app')
    .service('testeService', testeService)
})();
