Bindings made directly to an input's value property don't function

[sorvell]

<input value="{{foo}}"> works.

however, if I have this model, where the input property is a reference to the element:
model = {input: input};

a binding to input.value does not work:

<div>{{input.value}}</div>

Can this be fixed?

This question is equivalent to:

can changes in the value of input nodes' value property be observed by a PathObserver?

The answer is presently: no. Long term, form node values probably should Object.getNotifier(node).notify(), but it's not obvious to me there's a great way to polyfill this. E.g. having to inspect whether all objects along an observed path are input nodes is likely to slow down all observations in a way which probably isn't worth the trade off.

My suggestion is the same as adams. Create an intermediate object and bind input.value to it. Then bind that object to some place else.
