ShuduleUpdate on win32/android platforms

cocos2d-x JavaScript
1

So, here is some code, witch works fine on web, but when i run it on win32/android, update() function just do nothing. (using cocos2d-x 3.10 and the same was in 3.9)
(here is app.js)

var winSize = cc.winSize;
var ghostGameLayer;
var action = cc.moveBy(10, cc.p(0, 500));
var a = 0;
var gameLevelScene = cc.Scene.extend({
  onEnter: function() {
    this._super();
    var layer = new gameLevelLayer();
    this.addChild(layer);
  }
});

var gameLevelLayer = cc.Layer.extend({
  sprite: null,
  ctor: function() {
    this._super();
    var winSize = cc.winSize;
    var ghost = new cc.Sprite(res.ghost_png);
    var testLevelBackground = new cc.Sprite(res.testLevelBackground_png);
    testLevelBackground.x = winSize.width / 2;
    testLevelBackground.y = winSize.height / 2; 
    this.addChild(testLevelBackground, 0);
    ghost.x = winSize.width / 2;
    ghost.y = winSize.height / 2; 
    this.addChild(ghost, 0);
    var playButton = new cc.MenuItemSprite(
      new cc.Sprite(res.playButtonUnpressed_png),
      new cc.Sprite(res.playButtonPressed_png), null,
      this.onPlay, this);
    lolbutton = playButton;
    ghostGameLayer = ghost;
    var menu = new cc.Menu(playButton);
    menu.x = winSize.width / 4;
    menu.y = winSize.height / 4;
    this.addChild(menu);
    this.scheduleUpdate();
    var action = cc.moveBy(10, cc.p(0, 500));
    var a = 0;
    return true;
  },
  update: function(dt) {
    if (a==0){
      ghostGameLayer.runAction(action);
      a = 1;
    }
  },
  onPlay: function() {
  }
});

I know, my code looks pretty bad, but - i’m just start learning, so anybody can explain, why update(dt) - dont start any actions (i tried other things too, and got nothng)?

P.S.
Sorry for my english.
