>=RC.6

In RC.6 it should be supported to update the form model. Creating a new form group and assigning to myForm

[formGroup]="myForm"

will also be supported (https://github.com/angular/angular/pull/11051#issuecomment-243483654)

>=RC.5

form.reset();

In the new forms module (>= RC.5) NgForm has a reset() method and also supports a forms reset event. https://github.com/angular/angular/blob/6fd5bc075d70879c487c0188f6cd5b148e72a4dd/modules/%40angular/forms/src/directives/ng_form.ts#L179

<=RC.3

This will work:

onSubmit(value:any):void {
  //send some data to backend
  for(var name in form.controls) {
    (form.controls[name]).updateValue('');
    /*(form.controls[name]).updateValue('');*/ this should work in RC4 if `Control` is not working, working same in my case
    form.controls[name].setErrors(null);
  }
}
