events - jquery add more to a click function -

I have a function that is bound to some JavaScript pages for some page objects that are loaded on every page .

I need to add some more functionality to the already defined event handler. Here's an example of what I mean here.

With the currently defined click event the object closes the pop-up division on the screen. When it is clicked (only on this fixed page), I need to reset some elements on this page.

Therefore, I can easily open click events, and make a custom one reboot, but it will have to copy a lot of code from the original closed event

if worse Worse, I can do this, but I would like to save the copy of that code for this special case.

Is there any way, more code for any insights?

bind to another handler with just added functionality
