Listen to setter changes in model?

[sukhcha-in]

How can I make this reactive?
Changes are only reflecting when hot reloading.

My model:

class ProductModel {
  String name;
  ProductModel({
      required this.name
  })
  void setName(String name) {
    this.name = name;
  }
}

My controller:

class ProductController extends GetxController {
  late ProductModel product; //any way to make this observable without providing dummy data because my model is huge?

  @override
  void onInit() {
    super.onInit();
    //loads data from api and set product with data
    product = Product('old product name');
    //initialize another request to get fresh data
    updateProduct();
  }

  void updateProduct() {
    //some api call here
    product.setName('new product name');
  }
}

My view:

Obx(
  () => Text(controller.product.name)
)

Edit:
Solved using .update method
