AS3 Run gotoAndStop from a class

I have the problem with Actionscript 3.0 in Adobe Flash. I can't run "gotoAndStop" from a class (not document class). With the help of the Internet I tried several things, but none of them worked:

1)

MovieClip(root).gotoAndStop(3);

2)

package 
 {

import flash.display.MovieClip;

public class CustomClassName extends MovieClip
{
    public static var mainTimeline:MovieClip;
    public function CustomClassName()
    {
        // constructor code
    }
 }
}

3)

 public class np extends SimpleButton {
    var _root:MovieClip;

    public function np() {
        this.addEventListener(Event.ADDED_TO_STAGE,init);
        this.addEventListener(MouseEvent.CLICK,nextF);
    }

    private function init(e:Event):void{
        _root = MovieClip(this.root);
    }

    private function nextF(e:MouseEvent):void{
        _root.addEventListener(Event.RENDER,renderF);
        stage.invalidate();
        _root.nextScene();
    }

    private function renderF(e:Event):void {
        _root.gotoAndStop(5);
    }
}

I have these imports:

import flash.display.MovieClip;
import flash.display.Graphics;
import flash.display.Stage;
import flash.events.Event;

And if I run these lines of code:

trace('frame:',currentFrame);
super(this).gotoAndPlay(2);
trace('frame:',currentFrame);

... I get 0 as currentFrame as a result.

I have a class where I want to run gotoAndStop(2). And in my .fla file I have these in the first frame:

stop();
import Buzzer.*;

var buzzerClip:Buzzer = new Buzzer();
stage.addChild(buzzerClip);

But the code doesn't run the gotoAndStop function. And actually no error will be returned. Does someone has another idea?

The property root is null until the display object has been added to the display list.

So to adjust your first attempt:

public function MyDisplayObject()
{
    init();
}

private function init():void
{
    addEventListener(Event.ADDED_TO_STAGE, addedToStageHandler);
}

private function addedToStageHandler()
{
    MovieClip(root).gotoAndStop(3);
}
