                }
            };
        }]);

the createnouislider method is not firing. its giving an error on the update event which is giving an undefined.

it started working when i moved the update listener inside the createnouislider method. Also the connect variable was giving error so i just made it true for it to work. Might be a versioning issue.
This is the final working code:

angular.module("ui.materialize.nouislider", [])
        .directive("nouislider", ["$timeout", function($timeout){
            return {
                restrict: 'A',
                scope: {
                    ngModel: '=',
                    min: '@',
                    max: '@',
                    step: '@?',
                    connect: '@?',
                    tooltips: '@?',
                    behaviour: '@?'
                },
                link: function (scope, element, attrs) {
                    var modelIsArray = false;

                    var watchNgModel = scope.$watch('ngModel', function(newValue) {
                        if (newValue !== undefined) {
                            createNoUiSlider();
                            watchNgModel();
                        }
                    });

                    function createNoUiSlider() {
                        if (angular.isArray(scope.ngModel)) {
                            modelIsArray = true;
                        }

                        noUiSlider.create(element[0], {

                                },
                                from: function (number) {
                                    return Number(number);
                                }
                            }
                        });
                        element[0].noUiSlider.on('update', function(values, input) {
	                        $timeout(function() {
