I've been unable to implement this component within my MVC 5 project,

Keep getting the following error message:
Refused to execute inline script because it violates the following Content
Security Policy directive: "script-src 'self' ajax.googleapis.com
ajax.aspnetcdn.com". Either the 'unsafe-inline' keyword, a hash
('sha256-8fq9qms9vvqSd+oHtoALWzFES/gnzPLa/qckFLuLJbg='), or a nonce
('nonce-...') is required to enable inline execution.

ViewBag.Title = "Column";
}
