>>>Bear in mind that simply setting an inputs $dirty to false (even when there are no other dirty controls) will not cause the form $dirty to be re-evaluated. You may need something like this in your directive after $setPristine():

var dirty = false;

>>>    if (key[0] != '$') {
>>>        if (value.$dirty) {
>>>                dirty = true;
>>>        }
>>>    }
>>>});
>>>if (!dirty) {
>>>scope.theForm.$setPristine();
>>>}

This will reset the form if all inputs are pristine.....

For now I tried without that addition with a very slight change:

element[0].bind('blur', function () {
                    ctrl.$setPristine();
                    scope.$apply();
                })

e.g. I used element[0] instead of just element. But I am getting this error

TypeError: undefined is not a function

I can remove [0] if that's the source of the error. What do you think?
