title: Javascript removeEventListener not working
body: <p>I have the following code to add eventListener</p>
  
  <pre><code> area.addEventListener('click',function(event) {
                app.addSpot(event.clientX,event.clientY);
                app.addFlag = 1;
            },true);
  </code></pre>
  
  <p>It is working correctly as expected..Later in another function i tried to remove the event listener using the following code</p>
  
  <pre><code> area.removeEventListener('click',function(event) {
                app.addSpot(event.clientX,event.clientY);
                app.addFlag = 1;
            },true);
  </code></pre>
  
  <p>But the even listener is not removed..Why is it happening?Is there any problem with my removeEventListener()?
  Note:Here area is something like document.getElementById('myId')</p>
