title: Enabling a droppable via a function call
body: <p>In this fiddle - <a href="http://jsfiddle.net/zyUkd/26/" rel="nofollow">http://jsfiddle.net/zyUkd/26/</a></p>
  
  <p>I am attempting to enable the div "Hello 01" to accept a droppable when I click the button "Add Droppable" . I'm adding the droppable class "todrop" when the button is clicked but when I then drop an item on "Hello 01" the droppable event is not registered ?</p>
