Public bug reported:

Changing visibility of a page header does not seem to work if
head.visible is binded to another property and that property changes.

This code works (visibility changes on button click):

import QtQuick 2.4
import Ubuntu.Components 1.3

Page {
    id: root

    title: "Test page"

    head.visible: true

    Button {
        anchors.centerIn: parent
        onClicked: {
            if (root.head.visible) {
                root.head.visible = false
            }
            else {
                root.head.visible = true
            }
        }
    }
}

This one doesn't work:

import QtQuick 2.4
import Ubuntu.Components 1.3

Page {
    id: root

    property bool isHeaderVisible: true

    title: "Test page"

    head.visible: isHeaderVisible

    Button {
        anchors.centerIn: parent
        onClicked: {
            if (root.isHeaderVisible) {
                root.isHeaderVisible = false
            }
            else {
                root.isHeaderVisible = true
            }
        }
    }
}
