change event has different semantics than platform change on <input> elements

[sjmiles]

From MDN: "The change event is fired for , , and <textarea> elements when a change to the element's value is committed by the user. Unlike the input event, the change event is not necessarily fired for each change to an element's value." https://developer.mozilla.org/en-US/docs/Web/Events/change We are firing change event specifically on each each change to the value. It's probably better if we can match the platform semantics.
