Can't get ion-item-sliding to work

I have a tutorial for that here: http://www.joshmorony.com/ionic-2-how-to-create-a-sliding-delete-button-for-lists/

Also keep in mind that it may not work through the browser, I think there's some funkiness going on with click vs touch events in Ionic 2 right now, but if you look at it through the device emulator in Chrome or on an actual device it should work.
