you can create directive loop on necessary html elements under , add relevant events.

here's template started:

    angular.module("app", []).directive("changeform", function() {         var directive = {             restrict: 'a',             require: 'form',             link: function(scope, element, attrs, ctrl) {                 // here use element.find() elements                 // , use .on() on elements event                 // , use ctrl (which of type formcontroller)                 // set $dirty [https://docs.angularjs.org/api/ng/type/form.formcontroller]             }         }     }) 

and html should like:

<form name="myform" changeform> ... </form>
