How can I handle a button click on Apple Watch?

I have a button in my main interface. I did a ctl + drag from the button in the storyboard to the InterfaceController.m I then put an NSLog in the resulting method. This is what the code looks like

#import "InterfaceController.h"


@interface InterfaceController()

@end


@implementation InterfaceController

- (void)awakeWithContext:(id)context {
    [super awakeWithContext:context];
     NSLog(@"awakeWithContext!");
    // Configure interface objects here.
}

- (IBAction)Alarm {
    NSLog(@"Alarm!");

}

- (void)willActivate {
    // This method is called when watch view controller is about to be visible to user
    [super willActivate];
     NSLog(@"willActivate!");
}

- (void)didDeactivate {
    // This method is called when watch view controller is no longer visible
    [super didDeactivate];
     NSLog(@"didDeactivate!");
}

@end

I also took a screenshot with the logs appearing. No log occurs when a I press the Alarm button in the emulator.

enter image description here

UPDATE

I just followed the example in this video. "How to connect a WKInterfaceButton to an action in the code using Xcode" https://www.youtube.com/watch?v=CuCuL-a608w

I added this to the header - (IBAction)alarmPressed:(id)sender; I put this in the view controller

- (IBAction)alarmPressed:(id)sender
{
     NSLog(@"alarmPressed!");
}

I dragged the sent action select to the Interface Controller and selected alarmPressed. This still does not produce logs when pressed. Also traits includes "User Interaction Enabled"

Unfortunately the watchKit doesn't support the :(id)sender argument. so your IBAction should just read 

-(IBAction)alarmPressed{
    NSLog(@"alarmPressed!"):
}

also make sure that this dot is filled in. if it isn't that means you need to click on the hollow dot and drag it to your button.
