Unable To Ctrl-Drag From Table View Cell to Controller

I am learning about storyboards in iOS and I am having issues creating functions on cell presses in a Table View that is part of a tabbed view. I intend to share the view controller between the two tabs, and I have it working in the other tab, but when I try to ctrl-drag from the cell to the view controller I get nothing. Is there something I have to do to hook the table view up to my view controller that does not happen automatically?
