【解決方法】ゲームパッド API: ボタンイベントが発生しない

I have a bluetooth controller in which I've tested all the numbers of the buttons with this Gamepad tester:<a href="https://gamepadtester.net/"> Gamepad Tester</a> so I'm pretty sure the values of the buttons are correct. However, nothing seems to fire, the Gamepad is shown to be "connected", just the button events not working. Below is the code:

JavaScript

function gameLoop() {
  if (navigator.webkitGetGamepads) {
    var wgp = navigator.webkitGetGamepads()[0];

    if (wgp.buttons[12] == 1 || wgp.buttons[4] == 1) {
      console.log('move');
    }
};

gameLoop();

Where could I have wrong? I'm using Chrome so I have the webkit prefix. Could the Gamepad tester be showing me the wrong buttons? Thanks for your help.
