[Interest] QML objects and QMetaMethod

I have the following code :

Foo.qml :

    MyLib.MyObject {
      function createTree() { /* stuff */ }
      property string host: "ws://whatever.com"

cpp :

    namespace lib {
      class MyObject : public QObject { Q_OBJECT };
    QQmlComponent c(engine);
    c.setData("content of Foo.qml", QUrl());

    auto obj = c.createObject();
    QString host = QQmlProperty(obj, "host").read();

Reading the "host" property works fine so the QML object is correctly
instantiated. But the invokeMethod call gives me a warning :

    QMetaObject::invokeMethod: No such method 'lib::MyObject::createTree()'

The weird thing being: it works fine if I replace MyLib.MyObject with
QtObject on the QML side.
Of course I want to use some additional methods present in MyObject so this
is not a solution.

Anyone knows what is going on here ?
