Static class to change TextField

Question

Hi,
I'm trying to make a static class that will change the text written in a TextField inside a SWF file.
In this case I have a MovieClip with a TextField inside with a message. I want to be able to make a class that giving this TextField and a message, that will change in the button.
Certainly that I'm forgetting something obvious, I get the correct trace messages, but the textfield disappears. The initial text is "Start" and I want to change that to "OK". For now I just want to change the text, but after I want to be able to change the text format.
So far I have this:
package
          import flash.display.MovieClip;
          public class ChangeTextField extends MovieClip
                    public function ChangeTextField(_textField:Object, _text:String):void {
                    public static function change(_textField:TextField, _text:String):void {
                         trace("CHANGETEXTFIELD " + _textField); //Return "Start"
                         _textField.text = _text;
In another class I've loaded the swf and it's content is inside a MovieClip so that I can reference it. To change the TextField text I would do something like:
ChangeTextField.change(okButton.normal.label_tx, "OK");
trace(okButton.normal.label_tx.text); //Returns "OK"
By the trace messages everything is doing what it's supposed to do, but the TextField disappears.
Any idea?
Cheers.
