What you are looking for is $setPristine(). You'll find it in the docs here: http://docs.angularjs.org/api/ng/type/form.FormController

When a form first loads on the page it is in a state called pristine. You'll find that form.$pristine is true and form.$dirty is false. Once any changes have been made to any element that has an Angular binding, those values are reversed. While you can reset the form input values to their original state, doing so does not change either Angular form state. Making a call to form.$setPristine(); sets those form values back to their original state.
