how to call a JavaScript function in the callback URL (jsOAuth + twitter + non-PIN OAuth)

Question

Learning about OAuth, I came across a big question. How to call a JavaScript function in the callback url with jsOAuth?

When you click Connect to twitter, the login screen opens, then the Twitter authorize APP and after he simply calls the callback URL. I would like to close this window and call a JavaScript function on the page that originated.

See my tests

Code

oauth = OAuth({
            consumerKey: srv.key,
            consumerSecret: srv.secret,
            requestTokenUrl: srv.request_token,
            authorizationUrl: srv.authorize,
            accessTokenUrl: srv.access_token,
            callbackUrl: "http://ridermansb.kodingen.com/twitter.html"
        });
