C++ 调用js 这样有错么？ 咋没效果

JS：

 onLoad: function () {
            this.label.string = this.text;
            cc.log("====111");
        
            var customClass = cc.CustomClass.create();
            customClass.callback = function(i, j){
                //this.label.string = "callback";
                cc.log("customClass.callback: " + i + j);
            };
    var msg = customClass.helloMsg()
    //this.label.string = msg
    cc.log("customClass's msg is ===: " + msg)
    
    },

C++:

std::string CustomClass::helloMsg() {
	js_proxy_t * p = jsb_get_native_proxy(this);
    //jsval retval;
    JSContext* jc = ScriptingCore::getInstance()->getGlobalContext();
    //  定义参数，由两个参数
    jsval v[] = {
        v[0] = int32_to_jsval(jc, 32),
        v[1] =UINT_TO_JSVAL(88)
    };
    // 通过 ScriptingCore 封装好的方法实现回调，可以帮助我们节省很多细节上的研究
    ScriptingCore::getInstance()->executeFunctionWithOwner(OBJECT_TO_JSVAL(p->obj), "callback", 2, v);
	CCLOG("===IN HELLO MSG");
    return "Hello from CustomClass::sayHello";
}
