angularjs directive ngModel datepicker JavaScript

I'm having a hard time understanding I'm stuck on something that should probably be simple... I've been banging my head against this for hours. I'm working with AngularJS 1.8 and I've created a custom directive to wrap an external date picker library (let's say, 'jQuery Datepicker'). The issue I'm facing is that the selected date from the datepicker is not updating the ngModel correctly. I've tried using `ngModelController.$setViewValue()` method within the directive, but it seems that the model isn't reflecting the changes correctly after selection. Here's the relevant code snippet for my directive: ```javascript app.directive('datepicker', function() { return { restrict: 'A', require: 'ngModel', link: function(scope, element, attrs, ngModel) { // Initialize datepicker $(element).datepicker({ onSelect: function(dateText) { // Update ngModel when date is selected scope.$apply(function() { ngModel.$setViewValue(dateText); }); } }); // Update datepicker when ngModel changes ngModel.$render = function() { $(element).datepicker('setDate', ngModel.$viewValue); }; } }; }); ``` When I select a date from the datepicker, I can see the model updates correctly in the console logs, but the UI still shows the previous date instead of the newly selected one. The strange part is that if I inspect the model in the console, it is updated, but the view doesn't reflect this change unless I manually trigger a digest cycle. I've tried forcing a digest cycle with `$scope.$apply()` in various places, but that didn’t help either. Additionally, I’ve ensured that the date format is consistent between the datepicker and the model, so that shouldn’t be the issue. Is there something I'm missing in the directive implementation or a best practice that I might not be following? Any insight would be greatly appreciated! For context: I'm using Javascript on Linux. Is there a better approach? I'm working on a web app that needs to handle this. What's the best practice here? I'm working with Javascript in a Docker container on Ubuntu 20.04.
