title: jQuery .on() at ajax success
body: <p>I would like to bind <code>.on()</code> to an ajax "event", meaning that I'd like it to be triggered whenever an ajax response is successfully retrieved.
  I don't get how I could bind <code>.on()</code> to such an event. Do I need to use <code>load</code> like so?</p>
  
  <pre><code>$(document).on('load','#elementInsertedByAjax',function(){
      // will do something
  });
  </code></pre>
  
  <p>PS I do need to use <code>.on()</code> since the whole page is inserted by an ajax call.</p>
