Angularjs 1.6 with backend node js does not show data

On the frontend I wrote the following code

<table class="table table-condensed table-striped table-hover" id="example" >
      <tr ng-repeat="item in $ctrl.entity">
        <td class="acciones" data-title="'Acciones'">
        </td>
        <td data-title="'Nombre'">{{item.nombre}}</td>
        <td data-title="'Estado'">{{item.estado}}</td>
      </tr>
  </table>

I have reviewed with Postman and I obtain the data via array not by means of an object

Array(n)
0:{nombre: "XXXX", id_entidad:3}
1:{nombre: "XXBB", id_entidad:2}

and it does not show the information in the form
