How do you get Jquery to run with cascading dropdown lists?

Hi,

Have a cascading dropdown list (DDLB) that refreshes with results from after a selection is made from DDLA.

It also appends another list item with a value of -2 with text of not listed. The default value is -1 with text of make a selection

I finally have some working jquery that shows/hides a separate textbox column.

My question is, how do you make the JQuery load/run after the list has been received from user making a selection in DDLA?

The process would need to also run if the user changes their mind & makes a different selection in DDLA

Thanks in advance

Todd
