Apply actions when Window created by Qt.createComponent is closed/destroyed

In my project, the user can click a button in homepage to open a new Window (QtQuick.Window 2.2). I want the button to be disabled when the Window is created and enabled when it's closed/destroyed.

The problem is

Code sample:

Homepage.qml

import QtQuick 2.12


Item {

   id: homePageItem
   property var component: null
   property var obj: null

   RoundButton {
        id: windowBtn
        enabled: // some condition
        ...
        ...

        onClicked: {
            component = Qt.createComponent("Window.qml")
            obj = component.createObject(root)
            obj.show()
            // windowBtn.enabled = false

           }
     }
}

Window.qml

import QtQuick 2.12
import QtQuick.Window 2.2


Window {
    width: 600
    height: 600

    ...
    ...

    }

You can listen for signals from the object you created.

Window.qml

Window {
    width: 600
    height: 600

    signal closed()   // Create a new signal

    Component.onDestruction: {
        closed()      // Emit your signal when the object is destroyed
    }
}

Homepage.qml

        onClicked: {
            component = Qt.createComponent("Window.qml")
            obj = component.createObject(root)

            // Create a listener for your signal
            obj.onClosed.connect(()=> { windowBtn.enabled = true })

            obj.show()
            windowBtn.enabled = false
        }
