Update: As seen in one of the comments, it seems TEXT_INPUT is not the way to go, as it is “Dispatched after a control value is modified, unlike the textInput event, which is dispatched before the value is modified” check out the API

Acording to the Adobe API In Flash, by default a text field’s property is usualy set to “dynamic”, however if you change this property to “input” using the TextFieldType class, then it is possible to save user input for use in other parts of your appication – This is mainly useful when creating forms, or any application that need the user to define a text value somewhere else in the system.

In this tutorials example, the following code creates an imput text field called myFirstTextBox. As the user enters the text, An event is triggered, we will call this inputEvent.
To capture the string of text entered, we need an event handler – we shall call this inputCapture, it will capture the string and assign it a variable – then Flash Player or AIR displays the new text in another text field, called OutputBox.

  import flash.display.Sprite;
  import flash.display.Stage;
  import flash.text.*;
  import flash.events.*;

  public class CaptureInput extends Sprite
    private var myFirstTextBox:TextField = new TextField();
    private var OutputBox:TextField = new TextField();
    private var myText:String = "Type your text here.";

    public function CaptureUserInput()

    public function captureText():void
      myFirstTextBox.type = TextFieldType.INPUT;
      myFirstTextBox.background = true;
      myFirstTextBox.text = myText;
      myFirstTextBox.addEventListener(TextEvent.TEXT_INPUT, inputEventCapture);

    public function inputEventCapture(event:TextEvent):void
      var str:String = myFirstTextBox.text;

    public function createOutputBox(str:String):void
      OutputBox.background = true;
      OutputBox.x = 200;
      OutputBox.text = str;
