What should I do to make VS listen to me?

Question

Angular

I am writing a project in ASP.NET + AngualrJS in the studio 2017 and added a controller to the view as follows:

<div ng-controller="questionController">
                {{2+2}}
            </div>

Further in js'e I wrote the following lines:

var myApp = angular.module('myApp', []);
    function questionController($scope) {
$scope.test = "test";
    }

As a result, when I compile and run the project, it loads the old js file for me, where this controller does not exist and, accordingly, writes in the Google console that

angular.js:15019 Error: [$controller:ctrlreg] The controller with the name 'questionController' is not registered

What does she want? For the test, I did the same actions in a regular html file on the desktop and everything works, well, it’s understandable because html loads what I tell it to me. But the studio loads what it wants.
Studio restarted. does not load the modified js file from both kestrel and IIS Express.
I do not know what to do, it does not load the changed js files for me.
