setText in event

Hello! I have something like this in my SWT/JFace tutorial application:

Code:

---

                text = new Text(parent, SWT.LEFT);
                text.addVerifyListener(new VerifyListener()
                {
                        @Override
                        public void verifyText(VerifyEvent arg0)
                        {
                                text.setText("blah blah");
                        }
                });

---

Why the text isn't updated in event? (text has only letters, whitch I pressed, but dont contain the "blah blah" text)
