QAbstractListModel data to QML TableView why not shown through QQmlApplicationEngine

[kiwimess]

I want my data to be showed in QML in table. When I follow this example here: http://doc.qt.io/qt-5/qtquick-models...l-example.html and add the TableView and use QQuickView in main all data is showed fine.

import QtQuick 2.0
import QtQuick.Controls 1.2
 
Rectangle {
height: 300
width: 600
//![0]
    ListView {
        width: 200; height: 250
 
        model: myModel
        delegate: Text { text: "Animal: " + type + ", " + size }
    }
    //![0]
 
    TableView {
        y:150
        width: 600
        model: myModel
        TableViewColumn {
            role: "type"
            title: "Type"
            width: 200
        }
        TableViewColumn {
            role: "size"
            title: "Size"
            width: 200
        }
    }
}

import QtQuick 2.0
import QtQuick.Controls 1.2

Rectangle {
height: 300
width: 600
//![0]
    ListView {
        width: 200; height: 250

        model: myModel
        delegate: Text { text: "Animal: " + type + ", " + size }
    }
    //![0]

    TableView {
        y:150
        width: 600
        model: myModel
        TableViewColumn {
            role: "type"
            title: "Type"
            width: 200
        }
        TableViewColumn {
            role: "size"
            title: "Size"
            width: 200
        }
    }
}

QGuiApplication app(argc, argv);
 
    AnimalModel model;
    model.addAnimal(Animal("Wolf", "Medium"));
    model.addAnimal(Animal("Polar bear", "Large"));
    model.addAnimal(Animal("Quoll", "Small"));
 
    QQuickView view;
    view.setResizeMode(QQuickView::SizeRootObjectToView);
    QQmlContext *ctxt = view.rootContext();
    ctxt->setContextProperty("myModel", &model);
//![0]
 
    view.setSource(QUrl("qrc:view.qml"));
    view.show();
 
    return app.exec();

    AnimalModel model;
    model.addAnimal(Animal("Wolf", "Medium"));
    model.addAnimal(Animal("Polar bear", "Large"));

    QQuickView view;
    view.setResizeMode(QQuickView::SizeRootObjectToView);

    view.setSource(QUrl("qrc:view.qml"));
    view.show();

    return app.exec();

But when I made my own implementation and wanted to use QQmlApplicationEngine, I get all the data fine to ListView but TableView is empty. And I just don't get it. Is it because of QQmlApplicationEngine or what?

Ok, this is not in main, it is in other classes constructor (doesn't make difference, does it?).

QQmlApplicationEngine *engine = new QQmlApplicationEngine;
 
    ComboModel combo;
    QStringList lst;
    lst << "Geelikynnet" << "Ripset" << "Kampaus" << "Tatuointi" << "Kulmat";
    combo.setComboList(lst);
 
    LineModel rokmodel;
    rokmodel.addLine(Line("Kulmat", "155,00", "Heidi"));
    rokmodel.addLine(Line("Tatuointi", "255,00", "Heidi"));
    rokmodel.addLine(Line("Kynnet", "55,00", "Ann-Marii"));
    rokmodel.addLine(Line("Ripset", "5,00", "Ann-Marii"));
 
    QQmlContext *ctxt = engine->rootContext();
    ctxt->setContextProperty("rokmodel", QVariant::fromValue(&rokmodel));
    ctxt->setContextProperty("myModel", QVariant::fromValue(combo.comboList()));
    ctxt->setContextProperty("comboModel", &combo);
    ctxt->setContextProperty("product", this);
 
    engine->load(QUrl(QStringLiteral("qrc:/main.qml")));
    QObject::connect(engine->rootObjects().takeFirst(), SIGNAL(qmlSignal(QString, QString)), this, SLOT(buttonPressed(QString, QString)));
    QObject::connect(engine->rootObjects().takeFirst(), SIGNAL(listSignal(QString)), this, SLOT(listSignal(QString)));

QQmlApplicationEngine *engine = new QQmlApplicationEngine;

    ComboModel combo;
    QStringList lst;
    lst << "Geelikynnet" << "Ripset" << "Kampaus" << "Tatuointi" << "Kulmat";
    combo.setComboList(lst);

    LineModel rokmodel;
    rokmodel.addLine(Line("Kulmat", "155,00", "Heidi"));
    rokmodel.addLine(Line("Tatuointi", "255,00", "Heidi"));
    rokmodel.addLine(Line("Kynnet", "55,00", "Ann-Marii"));
    rokmodel.addLine(Line("Ripset", "5,00", "Ann-Marii"));

    QQmlContext *ctxt = engine->rootContext();
    ctxt->setContextProperty("rokmodel", QVariant::fromValue(&rokmodel));
    ctxt->setContextProperty("myModel", QVariant::fromValue(combo.comboList()));
    ctxt->setContextProperty("comboModel", &combo);
    ctxt->setContextProperty("product", this);

    engine->load(QUrl(QStringLiteral("qrc:/main.qml")));
    QObject::connect(engine->rootObjects().takeFirst(), SIGNAL(qmlSignal(QString, QString)), this, SLOT(buttonPressed(QString, QString)));
    QObject::connect(engine->rootObjects().takeFirst(), SIGNAL(listSignal(QString)), this, SLOT(listSignal(QString)));

I have very thin understanding about models, but I understood that QAbstractListModel is the best because the view is updated automatically if I add items to the list. ListView would be fine to me, but I dont get the text in columns.
