Angularjs - $watch issue

wish of those help Instead of returning it in anonymous function, apply $watch directly on scope objects-
code :
            function (cprValue) {


                //For at scriptet ikke skal faile første gang det bliver loadet
                //tjekker vi om medlemmet har skrevet noget i cpr feltet
                if (cprValue === undefined) {
                    return false;

                //Hent brugerens input og split dem op
                var cpr = cprValue.toString();

                //Hvis cpr undeholder en streg -

                var dd = +cpr.substr(0, 2); // 01
                var mm = +cpr.substr(2, 2); // 02
                var yy = +cpr.substr(4, 2); // 90

                //Calculate if 90 is > 50
                if (yy > 50) {
                    var year = yy + 1900;
                } else {
                    var year = yy + 2000;

                //Sæt fødselsdags datoen sammen så momentJS forstår det
                var final = mm + "/" + dd + "/" + year;

                //Beregn datoen og split resultatet op så vi kun får fødselsdags tallet
                var alder = moment(final, "MM/DD/YYYY").fromNow().split(" ")[0];

                //Vi clear ageToYoung feltet hvis det har været udfyldt
                //og disabler andenBetaler vinduet igen
                $scope.ageToYoung = "";
                $scope.hideSecondpayer = true;

                //Hvis personen er mellem 15 og 18 år så vis andenBetaler boksen
                if ((alder >= 15) && (alder <= 18)) {
                    $scope.hideSecondpayer  = false;
                    $scope.hideRegnrBarn    = true;
                    $scope.hideKontonrBarn  = true;

                } else if (alder <= 14) {

                    //Personen er ikke gammel nok, og vi skriver det derfor til kunden
                    $scope.ageToYoung = "Du skal minimum være 15 år gammel";

AngularJS : $watch not triggered on change ($scope issue with include page)

AngularJS : $watch not triggered on change ($scope issue with include page)

This might help you In this plunker, I reworked the code to allow the user to select either "Rear" or "Front", and the select list will dynamically update. The selected value is available as $scope.selected.item on the MainCtrl scope. (There was a lot of unnecessary code in the directive that I removed. onChange handlers aren't needed when ng-model is being used.)
code :
<name-value-select selected-item="selected.item" options="filterTypes">

app.directive('nameValueSelect', function () {
    return {
        restrict: "E",
        scope: {
            selectedItem: "=",
            options: '='
        template: ...
<name-value-select selected-item="selected.item" choice="choice.type"

app.directive('nameValueSelect', function () {
    return {
        restrict: "E",
        scope: {
            selectedItem: "=",
            choice:  "=",
            options: "=",
        controller: function($scope)  {
          $scope.$watch('choice', function (selectedType) {
            $scope.selectedItem = '';  // clear selection
            $scope.filterTypes = [];
            angular.forEach($scope.options, function (type) {
              if (type.Type === selectedType) {
            }, $scope.filterTypes);
            $scope.filterTypes.sort(function (a, b) {
              return a.Description.localeCompare(b.Description);
        template: '<select ng-model="selectedItem" ' +
         'ng-options="o.Description for o in filterTypes">' +
         '<option value="" selected="selected">Please Select</option>' +

hope this fix your issue That's because $watch is just watching the reference of scope.data.nodes, so no matter what you push or pop, the reference will not change.
Instead of using $watch, you can use $watchCollection. It will detect the length of the array.
code :
scope.$watchCollection('data.nodes', function(){
    return scope.render(scope.data, scope.query);

Any of those help Since attrs.authIf is invalid expression you may wrap it in a function
code :
scope.$watch(function() { return attrs.authIf; }, checkAuth);

          $scope.dir = 'initial value';
        .directive('dir', function() {

              scope.$watch(function() {
