Code not working

[enpstudios]

I am creating a XML driven thumbnail gallery. Which works fine with this code:

import fl.transitions.Tween;
import fl.transitions.easing.*;

var  fadeTween:Tween;

var imageText:TextField = new TextField();

var imageLoader:Loader;
var xml:XML;
var xmlList:XMLList;
var xmlLoader:URLLoader = new URLLoader();
xmlLoader.load(new URLRequest("data.xml"));

xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded);

function xmlLoaded(event:Event):void
{
	xml = XML(event.target.data);
	xmlList = xml.children();
	
	for(var i:int = 0; i < xmlList.length(); i++)
	{
		imageLoader = new Loader();
		imageLoader.load(new URLRequest(xmlList[i].attribute("thumb")));
		imageLoader.x = 25;
		imageLoader.y = i * 200 + 25;
		imageLoader.name = xmlList[i].attribute("source");
		addChild(imageLoader);
		imageLoader.addEventListener(MouseEvent.CLICK, showPicture);
		
	}
}

function showPicture(event:MouseEvent):void
{
	imageLoader = new Loader();
	imageLoader.load(new URLRequest(event.target.name));
	imageLoader.x = 250;
	imageLoader.y = stage.stageHeight / 4;
	addChild(imageLoader);
	imageText.x = imageLoader.x + 200;
	imageText.y = 600;
	for(var j:int = 0; j < xmlList.length(); j++)
	{
		if(xmlList[j].attribute("source") == event.target.name)
		{
			imageText.text = xmlList[j];
		}
	}
	
	fadeTween = new Tween(imageLoader, "alpha",None.easeNone,0,1,1,true);
	
}

imageText.autoSize = TextFieldAutoSize.LEFT;
addChild(imageText);

What my problem is, is I am trying to format the text in the dynamically created text field by doing this:

import fl.transitions.Tween;
import fl.transitions.easing.*;

var  fadeTween:Tween;

var imageText:TextField = new TextField();

var myFormat:TextFormat = new TextFormat();
myFormat.font = "Helvetica";
myFormat.color = "0xFF0000";
myFormat.bold = true;
myFormat.size = 25;
myFormat.kerning = 2;


var imageLoader:Loader;
var xml:XML;
var xmlList:XMLList;
var xmlLoader:URLLoader = new URLLoader();
xmlLoader.load(new URLRequest("data.xml"));

xmlLoader.addEventListener(Event.COMPLETE, xmlLoaded);

function xmlLoaded(event:Event):void
{
	xml = XML(event.target.data);
	xmlList = xml.children();
	
	for(var i:int = 0; i < xmlList.length(); i++)
	{
		imageLoader = new Loader();
		imageLoader.load(new URLRequest(xmlList[i].attribute("thumb")));
		imageLoader.x = 25;
		imageLoader.y = i * 200 + 25;
		imageLoader.name = xmlList[i].attribute("source");
		addChild(imageLoader);
		imageLoader.addEventListener(MouseEvent.CLICK, showPicture);
		
	}
}

function showPicture(event:MouseEvent):void
{
	imageLoader = new Loader();
	imageLoader.load(new URLRequest(event.target.name));
	imageLoader.x = 250;
	imageLoader.y = stage.stageHeight / 4;
	addChild(imageLoader);
	imageText.x = imageLoader.x + 200;
	imageText.y = 600;
	for(var j:int = 0; j < xmlList.length(); j++)
	{
		if(xmlList[j].attribute("source") == event.target.name)
		{
			imageText.text = xmlList[j];
		}
	}
	
	fadeTween = new Tween(imageLoader, "alpha",None.easeNone,0,1,1,true);
	
}

imageText.autoSize = TextFieldAutoSize.LEFT;
addChild(imageText);

imageText.setTextFormat(myFormat);

And the text doesn't format, what am I doing wrong?
