好像有不少toluafix_ref_function没有释放？

Studio
#1 


        LUA_FUNCTION handler = (  toluafix_ref_function(L,2,0));
        self->setFrameEventCallFunc(=](cocostudio::timeline::Frame* frame){
            toluafix_pushusertype_ccobject(L, frame->_ID, &frame->_luaID, (void*)frame, getLuaTypeName(frame, "ccs.Frame"));
            LuaEngine::getInstance()->getLuaStack()->executeFunctionByHandler(handler, 1);
        });
        
        return 0;





        LUA_FUNCTION handler = (  toluafix_ref_function(L,2,0));
        
        self->addEventListener(=](cocos2d::Ref* ref,CheckBox::EventType eventType){
            handleUIEvent(handler, ref, (int)eventType);
        });
        
        return 0;

lua_cocos2dx_ui_manual.cpp 还有不少
