  <!-- Empresas Tab -->
  <ion-tab title="Empresas" icon-off="ion-ios-home-outline" icon-on="ion-ios-home" href="#/tab/emp">
    <ion-nav-view name="tab-emp" class="has-footer"></ion-nav-view>
  </ion-tab>

</ion-tabs>

empresa.html

<ion-view view-title="Empresas">

  <!--search bar-->
  <div class="bar bar-subheader item-input-inset">
  <label class="item-input-wrapper">
    <i class="icon ion-ios-search placeholder-icon"></i>
     <input ng-model="pesquisar" placeholder="Pesquisa rápida...">
  </label>  
  </div>

  <ion-content class="padding">

    <ion-list style="margin-bottom:120px !important">
