Centering the sprite and getting touch response on it

Hey all, I was trying to position a sprite into the center of the scene and getting a touch response on it. But in the output, the sprite is showing in a side of the scene and the area of touch response is also different. I draw a red square on output where I am getting the touch response instead of getting it on the sprite. (v4 & vs2019) .
Here is my code:

AppDelegate.cpp

#include "AppDelegate.h"
#include "TouchScene.h"

USING_NS_CC;

AppDelegate::AppDelegate() {
}

AppDelegate::~AppDelegate()
{
}

bool AppDelegate::applicationDidFinishLaunching() {
    auto director = Director::getInstance();
    auto glview = director->getOpenGLView();
    if (!glview) {
        glview = GLViewImpl::create("Hello World");
        glview->setFrameSize(640, 480);
        director->setOpenGLView(glview);
    }

    auto scene = TouchScene::createScene();
    director->runWithScene(scene);

    return true;
}

void AppDelegate::applicationDidEnterBackground() {
}

void AppDelegate::applicationWillEnterForeground() {
}

TouchScene.cpp

#include "TouchScene.h"

USING_NS_CC;

Scene* TouchScene::createScene()
{
    auto scene = Scene::create();
    auto layer = TouchScene::create();
    scene->addChild(layer);

    return scene;
}

bool TouchScene::init()
{
    if (!Layer::init())
    {
        return false;
    }

    auto sprite = Sprite::create("Picture.png");
    sprite->setPosition(Vec2(Director::getInstance()->getVisibleSize().width / 2,
        Director::getInstance()->getVisibleSize().height / 2));
    
    // Add a "touch" event listener to sprite
    auto touchListener = EventListenerTouchOneByOne::create();
    touchListener->onTouchBegan = [](Touch* touch, Event* event) -> bool {

        auto bounds = event->getCurrentTarget()->getBoundingBox();

        if (bounds.containsPoint(touch->getLocation())) {
            std::stringstream touchDetails;
            touchDetails << "Touched at OpenGL coordinates: " <<
                touch->getLocation().x << "," << touch->getLocation().y << std::endl <<
                "Touched at UI coordinate: " <<
                touch->getLocationInView().x << "," << touch->getLocationInView().y << std::endl <<
                "Touched at local coordinate:" <<
                event->getCurrentTarget()->convertToNodeSpace(touch->getLocation()).x << "," <<
                event->getCurrentTarget()->convertToNodeSpace(touch->getLocation()).y << std::endl <<
                "Touch moved by:" << touch->getDelta().x << "," << touch->getDelta().y;

            MessageBoxA(0, touchDetails.str().c_str(), "Touched", MB_OK);
            
        }
        return true;
    };

    Director::getInstance()->getEventDispatcher()->addEventListenerWithSceneGraphPriority(touchListener, sprite);
    this->addChild(sprite, 0);

    return true;
}

And here is output:
