emitting multiple signals at once from c++ to qml

[erikm]

Hello,
I have a list of my onw QObjects in C++

QList<QObject *>

This list is exposed to QML by a wrapper class

 qmlRegisterSingletonType<ListManager> ("foo", 1, 0, "Lists",
            [](QQmlEngine *engine, QJSEngine *scriptEngine) -> QObject * {
        Q_UNUSED(engine)
        Q_UNUSED(scriptEngine)

        return new ListManager;
    });

In QML I iterate over that list to dynamically create a bunch of objects

...
for(var i=0; i < objects.length; i++) {
   var myCppObject = objects[i];
   var object = Qt.createQmlObject('MyQMLObject {}', parent);
   object.property = Qt.binding(function() {return myCppObject.property; });
...

As you can see I am using Qt.binding() to bind a property from the Cpp Object to the QML Object. This property is defined like this:

// myobject.cpp
    Q_PROPERTY(int property READ property NOTIFY propertyChanged)
signals:
    void propertyChanged(int newProperty);

Now when I change a bunch of objects in a loop in C++ I get the following behavior (in pseudo code):

//in cpp
emit propertyChanged(1); //for object 1
emit propertyChanged(2); //for object 2
emit propertyChanged(3); //for object 3
// in qml
onPropertyChanged 3 // for object 3
onPropertyChanged 3 // for object 1
onPropertyChanged 3 // for object 2

What am I missing?
Thank you,
erikm
