Angular. How to call a method from a script?

Question

Angular

Tell me how to do it right:
There is a controller and a view, in the form I edit the product, one of the parameters is edited through the slider (jQuery UI). How to keep track of its values ​​as the slider is moved?

Answer 1

We assign an id to the block with the controller and access the methods through it:
angular.element(document.getElementById('productsCtrl')).scope().method();

Answer 2

In fact, the correct way for Angular is to write a directive for the slider and through it already attach to the data.

Accessing elements directly is not a good way.
