Problem defining a QML type having a property being another QML type

Charby

I would like to create a plugin that publish 2 QML types : TypeA and TypeB.
I have created 2 QObject base class for TypeA and TypeB. The creation of the classes and plugin is running well but now I need that TypeB could have TypeA as a property (actually, TypeB is a QAbstractItemListModel base class and I would like to fill the model using methods of TypeA).

What I have done so far...
C++ side :

class TypeA : public QObject
{
    Q_OBJECT
    ...
}
class TypeB : public QAbstractListModel
{
    Q_OBJECT
    Q_PROPERTY( TypeA* client READ getClient  WRITE setClient NOTIFY clientChanged)
public:    
    TypeA* getClient() {
        return client;
    }
    void setClient(TypeA * _client){
        if (be)
            client = _client;
    }
signals:
    void clientChanged();
    ...
private:
    TypeA* client = nullptr;
}

and now from the QML side :

TypeA{
    id:myTypeA
}
TypeB{
   client:myTypeA
}

This is not working : setClient is never called.
note : I have defined others properties in TypeA and TypeB (QString, bool..) which are working ok - and I haven't found warning raised by the moc compiler.
Do you know what I am doing wrong ?

Replying to myself...The problem vanished after a clean -rebuild all...Probably a MOOC'ing cache issue. Sorry for the bothering !
