title: jQuery UI Dialog buttons
body: <p>when creating a dialog with buttons like:</p>
  
  <pre><code>buttons:    {
              'button text': function(){                              
                  // do something
              },
  </code></pre>
  
  <p>do I have access to the button within the click event handler?</p>
  
  <pre><code>$(this)
  </code></pre>
  
  <p>is the context/jQuery object of the whole dialog.</p>
  
  <p>I doubt I have to be such creative as</p>
  
  <pre><code>$(this).find('button').attr(...)
  </code></pre>
  
  <p>to disabled a button there ?</p>
