title: rails bootstrap popover click doesn't work
body: <p>I'm trying to use the popover like in <a href="http://twitter.github.com/bootstrap/javascript.html#popovers" rel="nofollow">twitter bootstrap example</a>, so when you click a button it appears, and when you click it it disappear.</p>
  
  <p>I have in application.js </p>
  
  <pre><code>//= require bootstrap-tooltip.js
  //= require bootstrap-popover.js
  $(function () {
  $('.popover-test').popover();
  </code></pre>
  
  <p>});</p>
  
  <p>And in my view _fof.html.erb</p>
  
  <pre><code>&lt;button class="popover-test" id="button1" data-content="Popover Content"&gt;
      &lt;%= 'ciao' %&gt;
  &lt;/button&gt;
  </code></pre>
  
  <p>But popover comes only on mouse over, and when I move on it disappear. 
  Have I to implement the function on_click in js?</p>
