Динамическое создание обьекта и добавление в StackView QML

qml, c++

Всем привет.
Столкнулся с такой проблемой, на стороне С++ я создаю динамически обьект, его получаю на стороне QML и нужно его добавить в StackView.
И как это сделать не могу придумать. Ниже кидаю крестовую часть и QML

TimerContainer::TimerContainer(QObject *parent)
        : QObject(parent)
{
    vec_ = new vector<CircleTimer*>();
    createTimer();
}

CircleTimer *TimerContainer::getTimer(int index)
{
    return vec_->at(index);
}

void TimerContainer::delTimer(int index)
{
    vec_->erase(vec_->begin() + index);
    emit sizeChanged(vec_->size());
}

void TimerContainer::createTimer()
{
    auto timer = new CircleTimer();
    vec_->push_back(timer);
    emit sizeChanged(vec_->size());
    emit addNewTimer(timer);
}

void TimerContainer::createTimers(int number)
{
    if (number != 0)
    {
        while (number != 0)
        {
            createTimer();
            --number;
        }
    }
}

int TimerContainer::size()
{
    return vec_->size();
}

QML

StackView
{
    id: timers

    property var currentTimer: QtObject
    property int currentIndex: -1
    property int targetId: 0

    function selectTimer(idx)
    {
        for (var i = 0; i < timerContainer.size; ++i)
        {
            //timerContainer.getTimer(idx).visible = (i === idx);
            //console.log("idx: " + i + " - " + timerContainer.getTimer(idx).visible)
        }
        currentTimer = timerContainer.getTimer(idx);
        currentIndex = idx;
    }

    //function addTimer(timer) {
    //    timer.parent = circletimercontent1;
    //    timer.anchors.fill = circletimercontent1;
    //}

    Component.onCompleted: {
        for (var i = 0; i < timerContainer.size; ++i)
        {
            timers.push(timerContainer.getTimer(i));
        }

        timers.selectTimer(0);
        timerContainer.addNewTimer.connect(timers.addTimer);

    }

    Connections
    {
        target: currentTimer
    }
}

Наткнулся где то на форумах на
var newComponent = Qt.createComponent(arg)
var newObj = newComponent.createObject(arg)
но не уверен может ли это мне помочь.

Буду признателен если тот кто с чем то подобным сталкивался поможет разобратся в этом.

for (var i = 0; i < timerContainer.size; ++i)
{
    timerContainer.getTimer(i).visible = (i === idx);
