title: Popover in bootstrap doesn't work
body: <p>I'm tring using bootstrap and I'm trying to implement popover effect on a link.
  Here is the code for the link</p>
  
  <pre><code>&lt;a href="#" class="btn btn-danger" rel="popover" title="Title of popover" data-content="some text to display"&gt;Link popover&lt;/a&gt;
  </code></pre>
  
  <p>And here is the js code that I'm using on the bottom of the page</p>
  
  <pre><code>&lt;script type="text/javascript" src="http://platform.twitter.com/widgets.js"&gt;&lt;/script&gt;  
  &lt;script src="js/jquery-1.7.2.min.js"&gt;&lt;/script&gt;
  &lt;script src="js/bootstrap-transition.js"&gt;&lt;/script&gt;
  &lt;script src="js/bootstrap-tooltip.js"&gt;&lt;/script&gt;
  &lt;script src="js/bootstrap-popover.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>Nothing happen I can just see the title in the normal tooltip window.
  Any idea ?
  Thanks </p>
