ngChange fires before the model changes if the model and change function are passed in via a directive

[nseegmiller]

If you create a directive that wraps an input field and pass the change function and model to the directive and pass it along to the input field, the change function will fire before the model is updated. This behavior seems to have existed all the way back to 1.2 or even before. When ngModelOptions and updateOn: blur, it still calls the change function before the model is updated. I've created a pretty simple Plunker to demonstrate the issue.
