Angular 1.5 Components with Form and $setPristine

I'm trying to use a form within a component in Angular 1.5

I have the form working, in that I have model binding and can get to the data on submit. So I'm 90% of where I want to be, what's missing is being able to reset the form correctly using $setPristine.

I've attempted a couple of approaches the first was passing in the form as an argument to the reset function.

form.html

<form name="$ctrl.userForm">
  ...
  <input class="btn btn-default" type="button" ng-click="$ctrl.reset($ctrl.userForm)" value="Reset" />
</form>

form.component.js

ctrl.reset = function(userForm) {
    ctrl.user = {};
    userForm.$setPristine // Cannot read property '$setPristine' of undefined
};

Full code in Plnkr

I also tried declaring $ctrl.userForm as an empty object $onInit, but that didn't seem to work either. With the $setPristine line removed the reset works in clearing the forms data but not it's state from an angular perspective.

Any ideas on what I'm missing?

From your plunkr you have the entire component declared bellow.

function formController() {
  var ctrl = this;
  ...

  ctrl.reset = function(userForm) {
    ctrl.user = {};
    userForm.$setPristine
  };

  ctrl.reset();
}

The error is originated from this line ctrl.reset(); where you call the method without sending the argument userForm. Also, you are using $setPristine in the wrong way and you don't have to pass the form as an argument either.

I sugest you to use the form declared on your controller like so:

angular
  .module('application')
  .component('mkForm', {
    templateUrl: 'form.html',
    controller: formController
  });

function formController() {
  var ctrl = this;
  ctrl.master = {};

  ctrl.update = function(user) {
    ctrl.master = angular.copy(user);
  };

  ctrl.reset = function() {
    ctrl.user = {};
    ctrl.userForm.$setPristine();
  };
}

Note: you don't have to call ctrl.reset(); because the pristine state is the default state.
