Multi-touch over buttons

Hi,

I want detect touch events for my buttons, but using multi-touch, multiple buttons can be pressed at the same time.

Im trying this, but no success, because while i press one, the other don't generate event:

void MainScene::createActionButton(const Vec2& position, int playerIndex) {
    auto button = ax::ui::Button::create("ui/button.png");
    button->setAnchorPoint(Vec2(0.5, 0.5));
    button->setPosition(position);
    button->ignoreContentAdaptWithSize(false);
    button->setContentSize(Vec2(200, 200));
    button->setTag(playerIndex);
    button->setTouchEnabled(false);

    this->addChild(button);
}

void MainScene::setupTouchControls() {
    auto touchListener = EventListenerTouchAllAtOnce::create();

    touchListener->onTouchesBegan = [this](const std::vector<Touch*>& touches, Event* event) {
        for (auto& touch : touches) {
            Vec2 touchLocation = touch->getLocation();

            auto nodes = this->getChildren();
            for (auto& node : nodes) {
                auto button = dynamic_cast<ax::ui::Button*>(node);
                if (button && button->getBoundingBox().containsPoint(touchLocation)) {
                    int playerIndex = button->getTag();
                    handlePlayerActionPress(playerIndex);
                }
            }
        }
    };

    touchListener->onTouchesEnded = [this](const std::vector<Touch*>& touches, Event* event) {
        for (auto& touch : touches) {
            Vec2 touchLocation = touch->getLocation();

            auto nodes = this->getChildren();
            for (auto& node : nodes) {
                auto button = dynamic_cast<ax::ui::Button*>(node);
                if (button && button->getBoundingBox().containsPoint(touchLocation)) {
                    int playerIndex = button->getTag();
                    handlePlayerActionRelease(playerIndex);
                }
            }
        }
    };

    touchListener->onTouchesCancelled = touchListener->onTouchesEnded;

    _eventDispatcher->addEventListenerWithSceneGraphPriority(touchListener, this);
}

Thanks for any help.

I found it:

 #if !defined(AX_TARGET_OS_TVOS)
     [eaglView setMultipleTouchEnabled:YES];
 #endif
