NSButton cannot setaction

I am trying to add an action to a NSButton but it is not working

I create my NSButtton programmatically:

-(NSView *)rowTable:(CGFloat) heightOnPanel :(NSString *) textValue: (CGFloat) width: (CGFloat) height :(int) intColor{
    NSView *viewce = [[NSView alloc] initWithFrame:CGRectMake(0, heightOnPanel, 320, 40)];
    NSButton *layerBt = [[NSButton alloc] initWithFrame:NSMakeRect(0, 0, width, height)];

    [layerBt setTitle:textValue];

    [layerBt setButtonType:NSMomentaryPushInButton];
    [layerBt setTarget:nil];
    [layerBt setAction:@selector(buttonPressed:)];
    [viewce addSubview:layerBt];

    return viewce;
}

Select allOpen in new window

and here is IBAction method:

- (IBAction)buttonPressed:(id) sender{
    NSLog(@"hello world");
}

Select allOpen in new window

Could you point me to what I am missing?

Thanks
