form ember.js guide.

you need call save() on objects, this.

votedown: function () {         console.log("voting down");         this.set('votes', this.get('votes') - 1);         this.save();     } 

edit: however, if used jsfiddle mentioned, not have data persistence related code. method not work. ember-data.
