Ionic checkbox doesn't react on clicks

I have a really simple view in my Ionic application:

<ion-view view-title="Search">
<ion-content>  
    <ul class="list">
      <li class="item item-checkbox">
         <label class="checkbox">
           <input type="checkbox">
         </label>
         Flux Capacitor
      </li>
   </ul>
</ion-content>
</ion-view>

Problems is, nothing happens when I push the checkbox?

EDIT: I found the problem, but I don't know why it doesn't work. When I add the following to my menu.html the checkbox stops working:

<ion-tabs class="tabs-positive tabs-icon-only">

  <ion-tab title="Home" icon-on="ion-ios-filing" icon-off="ion-ios-filing-outline">
    <ion-nav-view name="home"></ion-nav-view>
  </ion-tab>


</ion-tabs>

Can someone explain why this is? Actually it is only the line:

<ion-nav-view name="home"></ion-nav-view>

That ruins it..
