How to implement guide with two-way data binding in angularjs with nested controllers
I'm working with a question with two-way data binding in AngularJS where I'm using nested controllers... Specifically, I'm trying to bind a property from a parent controller to a child controller but it seems like the bindings aren't updating as expected. Here's a simplified version of my code: ```javascript angular.module('myApp', []) .controller('ParentCtrl', function($scope) { $scope.sharedValue = 'Initial Value'; }) .controller('ChildCtrl', function($scope) { // Trying to log the sharedValue from the parent console.log('In ChildCtrl, sharedValue:', $scope.sharedValue); }); ``` In my HTML, I'm doing the following: ```html <div ng-app="myApp"> <div ng-controller="ParentCtrl"> <input type="text" ng-model="sharedValue" /> <div ng-controller="ChildCtrl"> <p>Value from Parent: {{sharedValue}}</p> </div> </div> </div> ``` When I type into the input box, I expect the paragraph in the child controller to update automatically. However, it remains unchanged. I've tried using `$scope.$parent.sharedValue` in the child controller but that doesn't seem to work either. The console log shows `undefined` for `sharedValue` in the child context. I'm using AngularJS version 1.8.2. Is there something I'm missing regarding scope inheritance or two-way data binding in this scenario? Any help to get this working would be greatly appreciated! My team is using Javascript for this application.
