Ajax Not Working on Edit Method - asp.net-mvc

Question

I have an ajax method for a cascading drop down list, similar to country - state drop down list. It works fine on Create method, but I can't get it to work on Edit method. I get this error on Edit:
POST http://localhost/Submissions/Edit/SomeAJAXMethod 500 (Internal Server Error)
There is an extra /Edit in the path that makes it not work. It works just fine on Create. I tried to add ~/. I get these errors on Create and Edit method:
POST http://localhost/Submissions/Edit/~/SomeAJAXMethod 404 (Not Found)
I tried to add ../. I get this error on Create, works fine on Edit:
POST http://localhost/SomeAJAXMethod 404 (Not Found)
How do I make it work on both Create and Edit?
Below is my controller.
