How to use a signal on QML side

[serkan_tr]

I have a class in C++ side and I have passed this class to QML with qmlRegisterType. C++ class triggers a certain signal, how do I detect this trigger by QML
C++

    Q_PROPERTY(int pitch READ pitch WRITE setPitch NOTIFY pitchChanged)
.
.
.

QML

    MainRos{
        id:main_ros
        objectName: "main_ros_qml"
    }
    Connections{
            target:main_ros 
            pitchChanged: {
                console.log("Camera slider value changed:", value);
            }
        }

this code is not working.
