I'm not sure that I completely understand your question...
If some thing is not working when you click something in MVC I normally have a look at the html and see what controller/action you are trying to call and put a break point there so you can see what is happening.
And I have to add this too...
This is a really good tutorial on MVC4 if you have not seen this you really should.
