title: Callbacks on jQuery Tipsy hide / show
body: <p>I'm trying to set a callback function after tipsy opens / closes.</p>
  
  <pre><code>function addText()
  {
      $('#text').html('Tipsy is now open !');
  }
  
  $('.tipsy').tipsy(addText);   
  </code></pre>
  
  <p>I want addText() to run after tipsy opens, but it doesn't.</p>
  
  <p>Is there an easy way to do that without modifying tipsy core code ?</p>
  
  <p>Here is my jsfiddle : <a href="http://jsfiddle.net/Tqcgr/1/" rel="nofollow noreferrer">http://jsfiddle.net/Tqcgr/1/</a></p>
