title: jQuery event when element is created
body: <p>I'd like to trigger an event when an element is created.</p>
  
  <pre><code>$(document).on('load','#TB_title',function() {
      console.log('loaded');
  });
  </code></pre>
  
  <p>Is there an equivalent of this that works?</p>
  
  <p>I saw some people suggest livequery, but that seems heavy. </p>
  
  <p>Thanks.</p>
