Link a word inside a dynamic text!? Not possible thru actionscript?

Hi there!
I am using a specific scroller buttons for this dynamic box I have
create. So its build all with actionscript. But the text is written
inside the box.
The problem is that I can´t figure out how can I select one word
of the text to be able to link it to a new site.

This kirupa tutorial about “Links in a Dynamic Text Box”:
it seems that only works if you create a dynamic box on the stage and not thru actionscript!

Here is the code I am using.
Is there any code I can add here for links to work?

this.createTextField("contentdisplay_txt", this.getNextHighestDepth(), 162, 100, 240, 310);
contentdisplay_txt.multiline = true;
contentdisplay_txt.wordWrap = true;
contentdisplay_txt.embedFonts = true;
contentFormat = new TextFormat();
contentFormat.font = "Font_1";
contentFormat.size = 15;
contentFormat.color = 0x333333;
contentdisplay_txt.text = aboutme_txt.text;
//Remove user input text field
aboutme_txt._x = 3000;
//Remove Scroll buttons
if (contentdisplay_txt.maxscroll<=1){
	Scroller._x = 3000;
