Edit bitmap from AS3

This will be my second post and the second problem

I create editable Bitmap with this code:

var myrequest:URLRequest = new URLRequest("images/bmp1.jpg");
var myloader:Loader = new Loader();
myloader.load(myrequest);
var myBitmapaData:BitmapData;
myloader.contentLoaderInfo.addEventListener(Event.COMPLETE, imgLoaded);
 
function imgLoaded(e:Event):void{
    myBitmapaData = new BitmapData(myloader.width, myloader.height);
    myBitmapaData.draw(myloader);
    var Bmp:Bitmap = new Bitmap;
    Bmp.bitmapData=myBitmapaData;
    addChild(Bmp);

Everything has been very good loaded and I can see the efect in my swf. But the main thing that I want to do is fill the elements with different colors. I added listener to the stage, which has to do it, but it doesn't work:

stage.addEventListener(MouseEvent.CLICK, FillObject);
 
function FillObject(me:MouseEvent):void{
        myBitmapaData.floodFill(mouseX,mouseY,0x55cc33);
    } 

I haven't idea what is wrong. I should reload the picture ? If somebody have any idea I will be grateful.

I found the way but it's not enough for me. I load the picture to the library and create the linkage. Than all is ok.

var myBitmapData:kolorowanka1 = new kolorowanka1(839,598);
 
var BMP:Bitmap = new Bitmap(myBitmapData);
stage.addChild(BMP);
stage.addEventListener(MouseEvent.CLICK, FillObject);
 
function FillObject(me:MouseEvent):void{
        myBitmapData.floodFill(mouseX,mouseY,0x55cc33);
    } 

But I want to load pictures from disk.

I attached rar with fla and picture.
