title: Error when using x-editable with BS3
body: <p>I want to make a simple use of the plugin x-editable, following step by step what's to do in the official doc.</p>
  
  <p>It actualy worked fine when I was on Bootstrap 2, though, it doesn't work anymore on BS3 (even if I updated everything to the latest version etc.).</p>
  
  <p>So when I click on the link to trigger the editable popover, I got this error in firebug :</p>
  
  <pre><code>TypeError: this.$element.data(...) is undefined
  [...]/Bootstrap3/js/bootstrap-editable.js
  Line 154
  </code></pre>
  
  <p>Which is actually this line :</p>
  
  <pre><code>this.$element.data('popover').tip().addClass('editable-popover');
  </code></pre>
  
  <p>Btw, I'm using CakePHP, all the plugins (js and CSS) are declared etc...</p>
  
  <p>So I'm running out of idea, if someone knows about it, would be cool !</p>
  
  <p>Thanks !</p>
  
  <p>EDIT : Problem solved, just had to reload the cache... Old script was still in it so there was compatibility problems.</p>
