Set target of UIButton to IBAction not working (Objective-C)

Is there any reason the following code for setting the target of a UIButton to an IBAction programmatically shouldn't work?

.h

- (IBAction)googleIt:(id)sender;

.m 

UIButton *google = [[UIButton alloc] initWithFrame:CGRectMake(20.0, 15.0, 280.0, 40.0)];
[google addTarget:self action:@selector(googleIt:) forControlEvents:UIControlEventTouchUpInside];

(that's in view did load, this is after that) 

-(IBAction)googleIt:(id)sender {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.google.com"]];
}

Edit: added a : after googleIt, still doesn't work. When I add a button in storyboard and just connect it to the IBAction, that works, so the IBAction itself is not the problem.

Edit: full button code requested 

 UIButton *google = [[UIButton alloc] initWithFrame:CGRectMake(20.0, 15.0, 280.0, 40.0)];
[google addTarget:self action:@selector(googleIt:) forControlEvents:UIControlEventTouchUpInside];
[google setTitle:@"Google 'em" forState:UIControlStateNormal];
[google setTitleColor:[UIColor whiteColor] forState:UIControlStateNormal];
google.backgroundColor = [UIColor blackColor];
[charityInfo addSubview:google];

EDIT: DONE! User action not enabled. Can somebody put that answer and I'll markas true?

the selector for googleIt is missing the colon to indicate that it takes an argument

it should be

[google addTarget:self action:@selector(googleIt:) forControlEvents:UIControlEventTouchUpInside];

Edit, added from comments: the selector was part of the problem, but user interaction was not enabled on the view the button was contained in.
