.delegate()

.delegate( selector, eventType, handler ) Returns: jQuery

.delegate( selector, eventType, eventData, handler )

Description: Attach a handler to one or more events for all elements that match the selector, 

now or in the future, based on a specific set of root elements.

.delegate() has been superseded by the .on() method. For earlier versions, 

however, it remains the most effective means to use event delegation. 

More information on event binding and delegation is in the .on() method.

$( "table" ).delegate( "td", "click", function() {

$( this ).toggleClass( "chosen" );

});

is equivalent to the following code written using .on():

$( "table" ).on( "click", "td", function() {

$( this ).toggleClass( "chosen" );

});
