delayedEvent.reset(2) throws error

Hey fellow Snappers, I'm trying to use the sample script for Delayed Callback events from the API manual but I'm getting an error for:

09:53:10 [Scenarium] TypeError: cannot read property 'reset' of undefined
at [anon] (DestroyBalls.js:14) preventsyield

*script is attached to a scene object and triggered for Tapped (or OnAwake)

///////////////////

Script is pretty basic:

var delayedEvent = script.createEvent("DelayedCallbackEvent").bind(DestroyBall);



function DestroyBall(e) {

var ball = script.getSceneObject().getChild(0);

ball.destroy();

}

// Start with a 2 second delay

delayedEvent.reset(2);

Any ideas? Much appreciated!
