Onesignal click handler is not firing

I've added the bridge code to handle Onesignal In-App click events but it's not working.
gonative.onesignal.iam.setInAppMessageClickHandler(function() {
alert ('This is a test');
});

I've tried with our existing build and a brand new build. Neither of which fire the event.
BTW there is an error in your docs.It says hander instead of handler.
