How do I capture a Modal close button event

How do I capture a Modal close button event

Total NB here.
I have a function that opens a modal window, when one of many lightbox buttons is clicked.
Ajax will pull the info for each individual lightbox.

However, since I have several other buttons on the same page, it opens the "myLightbox-dialog" window.
Is there a way I can capture a different button click just before calling the dialgo('open')?

thank you in advance.

        $("#lightbox-manage-dialog").dialog({

            modal: true,
