Drag'n'drop for dynamically created elements (jQuery)?

In jQuery there is a good plugin jQuery UI Draggable, which allows you to create effects drag'n'drop. It works quite simply: it is necessary for any existing item to invoke the method .draggable():
$('#test').draggable();

If you try to call this method to dynamically added element, nothing happens:

$('body').append('New item'); $('#newblock').draggable();

New item will not be able to drag'n'drop. How to make here something like the analogue of the function .live () to dynamically created elements also react to these methods?
