title: Remove event listener from window object using jquery
body: <p>I am trying to remove <code>blur</code> and <code>focus</code> event listeners from window object using jquery's unbind function using:</p>
  
  <pre><code>function removeWindowEvents(){
      $(window).unbind('blur') ; 
      $(window).unbind('focus') ;
  }
  </code></pre>
  
  <p>I registered the event using Javascript:</p>
  
  <pre><code>function addEvents(){
  window.addEventListener('blur', function(){ document.title = "Blurred" ; });
  window.addEventListener('focus', function(){ document.title = "In Focus" ;}); 
  
  
  }
  </code></pre>
  
  <p>This however does not work. What am I doing wrong? I tested this is Mozilaa and Chrome(latest versions)</p>
