I am trying to write code that will pass some data from C++ engine to the Qml scripts via signal, but it looks like that I doing some thing wrong, because when I receive signal in Qml my object don't any method or properties! Look at that code:

Signaller - class that invoke signal:
signaller.h:

```
class Signaller : public QObject
{
    Q_OBJECT
public:
    explicit Signaller(QObject *parent = 0);
    Q_INVOKABLE void invokeSignal();
signals:
    void mysignal(TestClass test);
public slots:

};

```

signaller.cpp:

```
Signaller::Signaller(QObject *parent) :
    QObject(parent)
{
}

void Signaller::invokeSignal()
{
    TestClass s;
    emit mysignal(s);
}

```

TestClass - class that will be passed to Qml engine, and which must have test method in Qml script:

Test.h:

```
class TestClass : public QObject
{
    Q_OBJECT
public:
    explicit TestClass(QObject *parent = 0);
             TestClass(const TestClass& obj);
             ~TestClass();
     Q_INVOKABLE void test();

signals:

public slots:

};

Q_DECLARE_METATYPE(TestClass)

```

Test.cpp:

```
TestClass::TestClass(QObject *parent) :
    QObject(parent)
{
    qDebug()<<"TestClass::TestClass()";
}

TestClass::TestClass(const TestClass &obj) :
    QObject(obj.parent())
{
    qDebug()<<"TestClass::TestClass(TestClass &obj)";
}

TestClass::~TestClass()
{
    qDebug()<<"TestClass::~TestClass()";
}

void TestClass::test()
{
    qDebug()<<"TestClass::test";
}

```

Those 2 classes also registered in main function:

```
int main(int argc, char *argv[])
{
    // SailfishApp::main() will display "qml/template.qml", if you need more
    // control over initialization, you can use:
    //
    //   - SailfishApp::application(int, char *[]) to get the QGuiApplication *
    //   - SailfishApp::createView() to get a new QQuickView * instance
    //   - SailfishApp::pathTo(QString) to get a QUrl to a resource file
    //
    // To display the view, call "show()" (will show fullscreen on device).

    qmlRegisterType<TestClass>("Test", 1, 0, "Test");
    qmlRegisterType<Signaller>("Signaller", 1, 0, "Signaller");

    return SailfishApp::main(argc, argv);
}

```

That is my Qml file with test code:

```
import Signaller 1.0

Page {

    Signaller {
        id: sig
        Component.onCompleted: sig.invokeSignal()
        onMysignal: {
            console.log("signal",typeof test);
            console.log(typeof test.test);
        }
    }
}

```

And the log:

```
[D] TestClass::TestClass:6 - TestClass::TestClass() 
[D] TestClass::TestClass:12 - TestClass::TestClass(TestClass &obj) 
[D] TestClass::TestClass:12 - TestClass::TestClass(TestClass &obj) 
[D] onMysignal:41 - signal object
[D] onMysignal:42 - undefined
[D] TestClass::~TestClass:18 - TestClass::~TestClass() 
[D] TestClass::~TestClass:18 - TestClass::~TestClass() 

```

As you can see from log, TestClass.test field is empty after passing to the Qml. 
What I am doing wrong?
