Joystick button events aren't working?

            if (this.Joysticks.Count > 0) { 
 
                this.Joysticks[0].ButtonDown += (object sender, JoystickButtonEventArgs buttonEvent) =>
                {
                    Application.Exit();
                    MessageBox.Show("AHHH!");
                };
 
                MessageBox.Show(this.Joysticks[0].Description); 
            }
