AngularJS 1.8: Issues Binding a Complex Object in ng-model with Two-way Data Binding

I need some guidance on I'm not sure how to approach Hey everyone, I'm running into an issue that's driving me crazy... I'm working with a strange scenario with AngularJS 1.8 when trying to implement two-way data binding on a complex object using `ng-model`. I have a form with nested properties inside an object, and I'm unable to get the changes in the form reflected back to the original object. For example, I have the following structure: ```javascript $scope.user = { name: '', address: { street: '', city: '' } }; ``` I bind the form inputs to the user object like this: ```html <form> <input type="text" ng-model="user.name" placeholder="Name" /> <input type="text" ng-model="user.address.street" placeholder="Street" /> <input type="text" ng-model="user.address.city" placeholder="City" /> </form> ``` When I fill in the form, I expect the `user` object to update automatically. However, when I log the `user` object after making changes in the form, it's still showing the initial values. I've verified that the `ng-model` bindings are correct by inspecting the elements. I've also tried using `$scope.$apply()` to force a digest cycle after the changes, but that hasn’t helped either. Despite this, when I use a simple flat object instead (e.g., `user = { name: '', street: '', city: '' }`), everything works perfectly. Is there a specific limitation or common pitfall with nested objects and `ng-model` that I might be overlooking? Any insights or suggestions would be greatly appreciated!
