QtQuick and C++ datamodel

[creation]

For example, I have a class named MyClass that contains a variable named myModelVariable.
myModelVariable is a class that inherits QAbstractListModel.
As like many other class that inherits QAbstractListModel, there is always a list variable in it.
In my case, I use QVariantList, and it's empty when initialized.

MyClass has a function that connect to network and the result is a JSON list that I will use to update data in myModelVariable.


maybe this is example can describe my problem.

#ifndef MYCLASS_H
#define MYCLASS_H
 
#include <QObject>
#inclide <QNetworkAccessManager>
#include "mymodel.h"
 
class MyClass : public QObject
{
    Q_OBJECT
 
public:
    explicit MyClass(QObject *parent = 0);
 
    void getData();
 
signals:
 
public slots:
    void dataLoaded();
 
private:
    MyModel *myModelVariable;
 
    QNetworkAccessManager *manager;
 
};
 
#endif // MYCLASS_H

#ifndef MYCLASS_H
#define MYCLASS_H

#include <QObject>
#inclide <QNetworkAccessManager>
#include "mymodel.h"

class MyClass : public QObject
{
    Q_OBJECT

public:
    explicit MyClass(QObject *parent = 0);

    void getData();
    
signals:

public slots:
    void dataLoaded();

private:
    MyModel *myModelVariable;

    QNetworkAccessManager *manager;

};

#endif // MYCLASS_H

    connect(reply, SIGNAL(finished()), this, SLOT(dataLoaded()));

    if (!reply) {

    }
    else

        {

                //how to update qml listview here?
            }
        }
 
        reply->deleteLater();

My question is how can I update my ListView on qml?
Is it possibel to use property binding with NOTIFY?
if it's possible, what should I write in that function?

Btw, I'm still new to QtQuick and QML and I'm really thankful for any helps.
