angularjs - angular - ngModelController $formatters won't trigger. -

-

hey guys i'm having trouble wrapping head around ngmodelcontroller.

i have directive:

app.directive('emailvalidation', function () { return {     restrict: 'a',     require: 'ngmodel',     link: function (s, e, a, c) {         c.$parsers.push(function (value) {             return value.tolowercase();         });          c.$formatters.push(function (value) {             if (value) {                 return value.touppercase();             }         });         s.$watch('user.email', function () {});     } }; });

this is. $parsers work! minute type input lowercase. after goes through validation pipe. done! , can see i'm trying output upper case view still shown parser return

the html looks this. 

<form name='email' novalidate> <input type='text'          name='email'          placeholder='email address'         data-ng-model='user.email'          required         email-validation /> </form>

i'm pretty sure i'm missing need please help. in advance.
