title: Wrap the event handler in JQuery
body: <p>I have some inputs with OnBlur event handlers something like </p>
  
  <pre><code>&lt;input name="abc" tabIndex="5" class="datetime" onblur="if (CheckMode(this))__doPostBack('abc',''); else return false;"  /&gt;
  </code></pre>
  
  <p>In JQuery Form ready, I'd like to convert OnBlur event hanlder into something like</p>
  
  <pre><code> &lt;input name="abc" tabIndex="5" class="datetime" onblur="....; setTimeout(function(){if (CheckMode(this))__doPostBack('abc',''); else return false;},100);"  /&gt;
  </code></pre>
  
  <p>It means I'd like to wrap the current event handlers with some extra codes.
  I'd like to call the old code with setTimeOut() after doing some extra work.
  <br>
  If's possible to do on the client side like the above?<br>
  I've tried attr() , but it does NOT work.<br> 
  The contents are changed , but nothing happens onBlur.<br>
  Also, I think , I can't use Blur()/Live()/bind() in this situation, can I?</p>
