Drop event not firing in chrome

It seems the drop event is not triggering when I would expect.

I assume that the drop event fires when an element that is being dragged is releases above the target element, but this doesn't seem to the the case.

What am I misunderstanding?

http://jsfiddle.net/LntTL/

$('.drop').on('drop dragdrop',function(){
    alert('dropped');
});
$('.drop').on('dragenter',function(){
    $(this).html('drop now').css('background','blue');
})
$('.drop').on('dragleave',function(){
    $(this).html('drop here').css('background','red');
})

In order to have the drop event occur on a div element, you must cancel the ondragenter and ondragover events. Using jquery and your code provided...

$('.drop').on('drop dragdrop',function(){
    alert('dropped');
});
$('.drop').on('dragenter',function(event){
    event.preventDefault();
    $(this).html('drop now').css('background','blue');
})
$('.drop').on('dragleave',function(){
    $(this).html('drop here').css('background','red');
})
$('.drop').on('dragover',function(event){
    event.preventDefault();
})
