Current behavior

I have a form in Angular2 using the Data-Driven method, and when I use form.reset(), the controls are getting cleared, the values of the controls in an FormArray are getting cleared but the amount of the controls aren't (Inside a FormArray).

Expected/desired behavior

I expect that form.reset() will clear also the FormArray (reset their value and amount)

Reproduction of the problem
Plunker: http://plnkr.co/edit/RKWPWC7PBh8yNJvkcWWc

What is the expected behavior?

What is the motivation / use case for changing the behavior?

Please tell us about your environment:

• Angular version: 2.0.0-rc.5
• Browser: [all]
• Language: [TypeScript]

Any thoughts?

@seklyza The current reset() function mimics a regular HTML5 form reset, so it only clears existing inputs and doesn't remove any inputs that are added programmatically later.

If you want to remove the added controls, rebinding the FormGroup might be cleaner. #11051 will make this possible.

Closing, as #11051 gives you a way to do this.
