title: Ionic checkbox doesn't react on clicks
body: <p>I have a really simple view in my Ionic application: </p>
  
  <pre><code>&lt;ion-view view-title="Search"&gt;
  &lt;ion-content&gt;  
      &lt;ul class="list"&gt;
        &lt;li class="item item-checkbox"&gt;
           &lt;label class="checkbox"&gt;
             &lt;input type="checkbox"&gt;
           &lt;/label&gt;
           Flux Capacitor
        &lt;/li&gt;
     &lt;/ul&gt;
  &lt;/ion-content&gt;
  &lt;/ion-view&gt;
  </code></pre>
  
  <p>Problems is, nothing happens when I push the checkbox?</p>
  
  <p>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: </p>
  
  <pre><code>&lt;ion-tabs class="tabs-positive tabs-icon-only"&gt;
  
    &lt;ion-tab title="Home" icon-on="ion-ios-filing" icon-off="ion-ios-filing-outline"&gt;
      &lt;ion-nav-view name="home"&gt;&lt;/ion-nav-view&gt;
    &lt;/ion-tab&gt;
  
  
  &lt;/ion-tabs&gt;
  </code></pre>
  
  <p>Can someone explain why this is? 
  Actually it is only the line: </p>
  
  <pre><code>&lt;ion-nav-view name="home"&gt;&lt;/ion-nav-view&gt;
  </code></pre>
  
  <p>That ruins it..</p>
