title: How to unbind an jquery on('click','selector') event
body: <p>I've binded a class as follow,</p>
  
  <pre><code>$(document).on('click','.add-more',function(){
   alert('Do Something')
  });
  </code></pre>
  
  <p>My requirement forces me to use .on('click') instead of click, bind('click') etc...  Now I want to unbind the click event.  Hope my question is clear.  Thanks in anticipation for support.</p>
