angularjs directive scope ng-model JavaScript

I'm testing a new approach and I'm refactoring my project and I'm trying to implement I'm sure I'm missing something obvious here, but I'm having trouble with an AngularJS 1.8 custom directive that uses an isolate scope. The directive is supposed to wrap an input field and bind its value to a model in the parent scope, but I'm noticing that the ng-model is not updating as expected when the input changes. My directive looks somewhat like this: ```javascript app.directive('customInput', function() { return { restrict: 'E', scope: { model: '=' }, template: '<input type="text" ng-model="inputValue" />', link: function(scope) { scope.$watch('inputValue', function(newValue) { scope.model = newValue; }); } }; }); ``` However, even though I can see the input field displaying the initial value from the model, changes to the input field don't reflect back to the model. When I inspect the `scope.model` in the console, it remains unchanged after I type something into the input. I tried using `ng-model` directly on the input element and it worked fine, so I suspect the issue lies in the way I'm handling the two-way data binding in the directive. I also made sure to pass the model correctly from the parent scope like this: ```html <custom-input model="myModel"></custom-input> ``` I attempted to troubleshoot by adding a console log inside the `$watch`, but it isn't being triggered at all. The initial value is correctly set, but I'm not seeing any updates. I also checked that `inputValue` is defined within the directive's scope. Is there something I'm missing in setting up the isolate scope or handling the model binding? Any help would be appreciated! What's the best practice here? How would you solve this? I'd love to hear your thoughts on this. I'm on Windows 10 using the latest version of Javascript. What's the best practice here? Is there a better approach?
