title: Jquery live keyup not working
body: <p>I have text box</p>
  
  <pre><code>&lt;input type="text"  name="extraQty0"  class="extraEvent" value="1"/&gt;
  </code></pre>
  
  <p>used following code </p>
  
  <pre><code>$(".extraEvent").live('keyup',function(){
     alert('test');
  });  
  </code></pre>
  
  <p>This is not working But if i use 'click'   instead of 'keyup' the alert will work. What could be wrong?</p>
