title: Removing the Event Listener on a Button programatically
body: <p>I have a Button which is registered with a <code>onclick</code> event as shown </p>
  
  <pre><code>&lt;Input type="Button" name="Register" Value="Register" onclick="CallMe();"/&gt;
  </code></pre>
  
  <p>Is it possible to programatically remove or deregister the onclick event on this Button?</p>
