> They can be bubbled, cancelled etc. No they can't be bubbled, there is only one DOM node, they could be cancelled but that has little point because again there is only one DOM node. You could stop immediate propagation but that's just really annoying in this pattern
Note that using DOM events has a seriously large run-time overhead. Also note that dean edwards has covered this topic in detail : http://dean.edwards.name/weblog/2009/03/callbacks-vs-events/ Your also dispatching the same event multiple times. Which won't work on some browsers. Your also relying on DOM2 events and have no fallback for IE this._evt = document.createEvent('Event'); this._evt.initEvent('change',true,true); Note that you can create a CustomEvent instead and initialize that custom event with a details object. Model.prototype.set = function(key,val){ this._fields[key] = val; var evt = document.createEvent("CustomEvent"); evt.initCustomEvent("modelChange", true, true, { key: key, val: val }); this.domnode.dispatchEvent(evt); }; You can then listen on "modelChange" and get the data through event.detail.
