cocos2d js v3.2的shcedule好奇怪啊，为什么调用次数比repeat多呢

Cocos2d-x JavaScript
#1

我的代码

dequeueChecked:function(customnum){
        MessageManager.customnum = customnum;
        queueLayer.unscheduleAllCallbacks();
        queueLayer.schedule(MessageManager.dequeueRadio, 5, 1,0);
    }



```


log输出如下：
JS: 正在叫号
JS: /Users/123/Documents/cocos/EasyorderQueue/runtime/mac/EasyorderQueue Mac.app/../../../src/utils/MessageManager.js:14:Error: js_cocos2dx_JSJavaBridge : call result code: -5

并且在输出第一行的时候，延时了5s左右。
