IBAction not being called

I am building an app with interface builder for the iPad. The scroll view takes up most of the screen except for a small portion at the bottom. Scrolling is enabled downwards. In the small portion on the bottom (not inside the scrollview), there is a UIButton that is connected to an IBAction: ``` - (IBAction)submit:(id)sender; ``` And implemented as follows: ``` - (IBAction)submit:(id)sender { NSLog(@"submit called"); } ``` I have connected up IBActions to buttons in IB countless times and never had a problem... But for some reason this is not getting called. I hooked it up by selecting the Button->connections inspector -> touch up inside -> files owner -> submit... Has anyone had this problem?
