Answer 1

<ion-content class="fondo has-subheader">     
    <div class="bar subheader item-input-inset bar-light">
        <label class="item-input-wrapper">
          <input type="text" ng-model="search" placeholder="Buscar">
        </label>
      </div>
      <ion-list>
        <ion-item class="button button-icon center" ng-repeat="cate in categorias | filter : search" type="item-text-wrap" href="#/tab/categoria/{{cate.id}}" > 
           <img class="img_cat" ng-src="{{cate.imagen}}" >
         <h2 class="categoria_n">{{cate.nombre}}</h2>
        </ion-item>
      </ion-list>
  </ion-content>

And try ui-sref in replace of href="#/tab/categoria/{{cate.id}}"
