How to fix $scope not updating in nested directives with isolate scope in AngularJS?
I'm working with AngularJS 1.8.2 and I'm running into a problem where my nested directives aren't updating the parent scope as expected when I use isolate scope. I have a parent directive that contains a child directive, and I'm trying to pass data from the parent to the child using an isolate scope. The child directive is supposed to update a value in the parent scope, but it seems that the changes are not being reflected in the parent after the child directive updates it. Here's the relevant part of my code: ```javascript app.directive('parentDirective', function() { return { restrict: 'E', scope: {}, template: '<div>Parent Value: {{ parentValue }} <child-directive parent-value="parentValue"></child-directive></div>', link: function(scope) { scope.parentValue = 'Initial Value'; } }; }); app.directive('childDirective', function() { return { restrict: 'E', scope: { parentValue: '=' }, template: '<button ng-click="updateParentValue()">Update Parent</button>', link: function(scope) { scope.updateParentValue = function() { scope.parentValue = 'Updated Value'; }; } }; }); ``` When I click the button in the `childDirective`, I see the `parentValue` in the `childDirective` being updated, but the value in the `parentDirective` remains 'Initial Value'. I tried using `ng-bind` instead of interpolation for the parent value, thinking it might help with the digest cycle, but that didn’t change anything. I'm not seeing any console errors either. What am I missing here? Is there something specific I need to do to ensure the parent scope is updated correctly?
