jQuery delegate and custom events

Question

I'm having issues binding a custom event to a delegate control

Any normal day I use the plugin like this

$(".galleryImage").swipe({
    swipeLeft: function (event, direction, distance, duration, fingerCount) {
        self.changeImageRight('swipe');
    },
    swipeRight: function (event, direction, distance, duration, fingerCount) {
        self.changeImageLeft('swipe');
    },
    threshold: 75 // px before events are triggered
});

If I bind it like this it works

$($galleryImageContainer).delegate('.galleryImage', 'click', function () {
    // ... magic stuff
});

But if I use swipe it doesn't

$($galleryImageContainer).delegate('.galleryImage', 'swipe', function () {
    // ... magic stuff
});

Is there a way to bind to custom events like this?
