Variable and callback function

Hi!

Could you help me?

The problem:

There is a class (singleton), where I load assets by

loader

 .add("assets/slotParams.json")

.load(this.setup);

In this callback function “setup” I change boolean variable from false to true, but when I want to get it from other class, there are no changes. How can it be?

Of course graphics show good.

 The example of code:

(class with graphics and changed variable "lp"):

class Graph
{	
    private bit:Bitte;
    private lp:boolean;	//variable that should be change
    get loadedProcess():boolean 
    {	 return this.lp;    }
    set loadedProcess(res:boolean) 
    {    this.lp = res;    }
    
	//stage & engine parts
	public Container;
	public autoDetectRenderer;
	public loader;
	public resources;
	public TextureCache;
	public Texture;
	public Sprite;
	public Text;
	public Graphics;
	public stage:PIXI.Container;	
	
	private static instance:Graph;
	private static ok2Create:Boolean=false;
	public static getInstance():Graph
	{
            if(!this.ok2Create)
            {
                this.instance = new Graph();
                this.ok2Create=true;
            }        
            return this.instance;
	}
	
	private constructor()
	{	
        this.loadedProcess=false;
        	
        Container = PIXI.Container;
        autoDetectRenderer = PIXI.autoDetectRenderer;
		loader = PIXI.loader;
		resources = PIXI.loader.resources;
		TextureCache = PIXI.utils.TextureCache;
		Texture = PIXI.Texture;
		Sprite = PIXI.Sprite;
		Text = PIXI.Text;
		Graphics = PIXI.Graphics;

		stage = new Container(); 
		renderer = autoDetectRenderer(1140, 768);

		renderer.backgroundColor = 0xFFFFFF;
		document.body.appendChild(renderer.view);

	}
        
    public loading():void
    {
            loader
		  .add("assets/slotParams.json")
		  .load(this.setup);
    }
        	
    private setup():void //callback function
    {
         this.loadedProcess=true; //not worked when asked this var from another class
    }
}

 Class with asking for this variable (in alert I take "false" each time);

class AssetsLoader
{
    private graph:Graph;
    private timme:number;   

    constructor()
    {
        this.graph=Graph.getInstance();
        this.timme=1;
    }  

    public goLoad():void
    {
        if (this.timme==1)
        {
            this.timme=2; 
            this.graph.loading(); 
        }

        if (this.timme==2)
        {
            alert("assets loader this.graph.loadedProcess="+this.graph.loadedProcess);
            if (this.graph.loadedProcess)
            {
                alert("win");
                this.timme=3;
            }
        }

        if (this.timme==3) 
        {   
        }  
}

function goLoad() loop.

Thank you in any case.
