implement a way to add controller functions as handlers with the existing rules respected but it's a bit dirty I will change the implementation and move the mvc2 to mvc and make the api builder's PartyFunc to be a critical part of the controller and the mvc2.Mvc bind values should be also respected to the controller and more
