Definition and Usage
The delegate() method attaches one or more event handlers for specified elements that are children of selected elements, and specifies a function to run when the events occur.
Event handlers attached using the delegate() method will work for both current and FUTURE elements (like a new element created by a script).
As of jQuery version 1.7, the on() method is the preferred method for attaching event handlers for selected elements.
