Setting up the onTap feature for an app

I'm trying to set up a feature on an app I'm working on where something happens when the user taps on the screen.  I've got a variable pToggle which, when the value is 1, starts the event.  I'm attempting to simulate the app on Venu 3 and I've got the Input Delegate but nothing yet on the view.mc, which I'm sure I will need to link to get the action to work.  Here is my code for the Input Delegate.  I could not find anything else in the documentation for the view.mc part - please advise.

class AppInputDelegate extends WatchUi.InputDelegate {

    function onTap(clickEvent) {
        System.println(clickEvent.getType());
        System.println("Screen tapped!");
        pToggle = 1;
        return true;
    }


}
