It's not possible to remove a value from <input type="number"> programatically.

[RobertSzymacha]

Although one can remove the value from an <input type="number"> manually (e.g. by pressing backspace), it's not possible to do it from Dart code, as all the values such as null, NaN are simply ignored (see lib/directive/ng_model.dart).

There should be a way to clear that value in Dart code.

How would we do this outside of AngularDart? e.g. can you remove the number with plain dart:html?
