Gamepad OnConnected Only Fired First Browser Seesion

The gamepad attachControl uses: new BABYLON.Gamepads((pad: BABYLON.Gamepad) => { this.onGamepadConnected(pad); });

but this.onGamepadConnected ONLY gets fired ONCE per browser session... If you refresh the page page it never gets fired thus the game pad no longer works... If i totally close down the browser and restart it works again because new instance of browser... What can we do about that???
