Hi,

AFAIK, you can do it in following ways:

Using "Connect()":http://doc.qt.io/qt-5/qtqml-syntax-signals.html#connecting-signals-to-methods-and-signals
Using "Connections()":http://doc.qt.io/qt-5/qml-qtqml-connections.html

An example :
@
Item {
id: item
width: 100
height: 150

signal sendMessage(string msg)

Loader {
    id: loader
    width: 100
    height: 100
    sourceComponent: comp
    Component.onCompleted: item.sendMessage.connect(loader.item.setText) //comment Component.onCompleted if using Connections and vice versa
}

// Connections {
// target: item
// onSendMessage: {
// loader.item.setText(msg)
// }
// }

Component {
    id: comp
    Rectangle {
        anchors.fill: parent
        color: "red"
        function setText(msg) {
            mytext.text = msg
        }

        Text {
            id: mytext
            anchors.centerIn: parent
        }
    }
}

Button {
    text: "Click Me"
    y: 110
    onClicked: item.sendMessage("Hello Qt")
}

}
