Call function from frame in other QML file

[BlueKenny]

How can i call a function from another file ?
My Pyotherside Handler is executed for sure, but my function "antwortGetDialogs" isn't executed...

I removed everything that isn't important for my question.
Hope someone can help me

this is my Main.qml :

import QtQuick 2.2
import io.thp.pyotherside 1.2
import QtQuick.Controls 1.1

ApplicationWindow {
id: mainWindow

StackView {
    id: view
    initialItem: frameDialogs
    anchors.fill: parent

    Component {
        id: frameDialogs
        Dialogs {id: dialogsWindow}
    }
}

Python {
    id: python
    Component.onCompleted: {
        addImportPath(Qt.resolvedUrl('./'));
        importModule('Main', function () {});

        setHandler("antwortGetDialogs", frameDialogs.Dialogs.antwortGetDialogs);
    }
}

}

my Dialogs.qml :

import QtQuick 2.2
import io.thp.pyotherside 1.2
import QtQuick.Controls 1.1

Rectangle {
id: window

function antwortGetDialogs(item) {
    console.warn("func antwortGetDialogs")
}

}
