//			    		UiApplication.getUiApplication().popScreen();
			    		Dialog.alert("Grocery Clicked");

	    public int indexOfList(ListField list, String prefix, int string) 
	        return _listElements.indexOf(prefix, string);

Re: List row clicking is not working in the popup screen

don't return false when not handling navigationclick, return super.
use the debugger to check if your navigationclick handler is called.
