angular.module('UserValidation', []).directive('validPasswordC', function () {
return {
require: 'ngModel',
link: function (scope, elm, attrs, ctrl) {
ctrl.$parsers.unshift(function (viewValue, $scope) {
var noMatch = viewValue != scope.myForm.password.$viewValue
ctrl.$setValidity('noMatch', !noMatch)
})
}
}
})
</script>

Answer

Hope this helps. You should return noMatch.

<script>
var app = angular.module('myapp', ['UserValidation']);

angular.module('UserValidation', []).directive('validPasswordC', function () {
return {
    require: 'ngModel',
    link: function (scope, elm, attrs, ctrl) {
        ctrl.$parsers.unshift(function (viewValue, $scope) {
            var noMatch = viewValue != scope.myForm.password.$viewValue
            ctrl.$setValidity('noMatch', !noMatch);
            return (noMatch)?noMatch:!noMatch;
        })
    }
    }
})
</script>
