cocos2d-x pageView터치 질문입니다.

Question

 PageView* pageView = PageView::create();
    pageView->setTouchEnabled(true);
    pageView->setSize(Size(winSize.width,winSize.height));
    //pageView->setAnchorPoint(Point(0,0));
    //pageView->setPosition(Point(winSize.width/2,winSize.height/2));
    
    for (int i = 0; i < 7; i++) {
        
        int position = i + 1;
        int tag = i + 100;
        char res[15]={0};
        sprintf(res, "continent%d.png",position);
        
        auto layout = Layout::create();
        layout->setSize(winSize);
        //layout->setPosition((Point(winSize.width/2,winSize.height/2)));
        
        
        Sprite* imageView = Sprite::createWithSpriteFrameName(res);
        imageView->setPosition(Point(winSize.width/2,winSize.height/2));
        imageView->setScale(3);
        imageView->setTag(tag);
        
        _touchListener = EventListenerTouchOneByOne::create();
           _touchListener->setSwallowTouches(true);
           _touchListener->onTouchBegan = CC_CALLBACK_2(SelectContinent::onTouchBegan, this);
           EventDispatcher* dispatcher = Director::getInstance()->getEventDispatcher();
           dispatcher->addEventListenerWithSceneGraphPriority( _touchListener, imageView);

        continent_img.pushBack(imageView);
        
        layout->addChild(imageView);
        
        pageView->addPage(layout);
        
    }

현재 pageview 구현코드가 저렇게 되어있는데요. imageView를 클릭해도 이벤트가 발생 안하는데 뭐가 문제인건가요??
