How can i use multiple controller?


I am working on one project where i have started using angular with MVC 4.0.

During development i found that project created with this tool uses only one controller i.e. home controller.
In my situation i wanted to have one more controller and that needs to be used inside angular. I have added another controller and changed routing in angular and change code for view. When I run code I can see my view but somehow angular tries to use controller name as function show me following error:

Error: [ng:areq] Argument 'ProjectController' is not a function, got undefined

ProjectController is angular controller.
