Tabs are not clickable , how to enable tab

I am using latest ionic and using below code

  <div class="tabs tabs-icon-only">
        <a nav-clear class="tab-item disable-user-behavior active" title="Home" nav-clear ui-sref="app.home">
          <i class="icon ion-home"></i><span class="tab-title ng-binding" ng-bind-html="title"></span>
        </a>
        <a nav-clear class="tab-item disable-user-behavior" title="Chat" icon-on="ion-ios7-filing" icon-off="ion-ios7-filing-outline" ui-sref="app.orders">
          <i class="icon ion-filing"></i><span class="tab-title ng-binding" ng-bind-html="title"></span>
        </a>
        <a nav-clear class="tab-item disable-user-behavior" title="Drink" icon-on="ion-ios7-filing" icon-off="ion-ios7-filing-outline" ui-sref="snd.drink">
          <i class="icon ion-wineglass"></i><span class="tab-title ng-binding" ng-bind-html="title"></span>
        </a>
      </div>

I have added above content in a view template before </ion-view>
I am not able to click on tabs in my view .
