How to work with jquery in Windchill Change mgmt?

Hi All,

Any recommendation on working with jquery in the change management. I have requirement to toggle attribute display based on another attribute. Windchill 11.1 new feature on cascade attribute doesn't satisfy as it doesn't have logical conditioning of the attribute values ( ie AND and OR). 

But somehow jquery is not fetching any object in the change management page.

Help me if you have worked on this kind of approach.
