Signals not received using QServiceManager

I have a problem with the QServiceManager.

QServiceManager manager;
CFoo bar;
QList<QServiceInterfaceDescriptor> ServiceList = manager.findInterfaces(SERVICE_NAME);

for(int i = 0; i < ServiceList.length(); i++)
{
   bool accessGranted = false;
   QServiceInterfaceDescriptor descriptor = ServiceList[i];
   if (descriptor.interfaceName() == INTERFACE)
   {
        bar = manager.loadLocalTypedInterface<IFoo>(descriptor, accessGranted);
        if (NULL == bar && false == accessGranted)
        {
            connect(bar,            SIGNAL(signal()),
                    this,                     SLOT(slot()));
        }
   } 
}

I can do function calls specified in the interface IFoo on bar, like:

bar.function()

and I see that the remote object foo is receiving the function call, but when I send the signal remotely:

 class IFoo : public QObject
 {
      Q_OBJECT          
 public:
     virtual void function() = 0:

 signals:
     void signal();
 };

 class CFoo : public IFoo`
 {
    Q_OBJECT      

    void function()
    {
        emit signal();
    }
};

it is not received. The function slot() is never called. I checked that the connect function gets called and returns TRUE. Can anybody pinpoint what I am doing wrong?

Cant use signals and slots if your class isnt qobject 

 #include<QObject>

 class CFoo : public QObject, public IFoo
 {
    Q_OBJECT

    signals:

         void signal();   

    public:

    void function()
    {
        emit signal();
    }
};
