Public bug reported:

When trying to assign a binding value to head.sections.selectedIndex, this value is not updated when the bound value changes.
See the example program below:

import QtQuick 2.4
import Ubuntu.Components 1.3

MainView {
    id: mainview
    objectName: "mainView"

    width: units.gu(100)
    height: units.gu(75)

    Page {
        id: mainPage
        title: "selectedIndex: " + head.sections.selectedIndex + " should be: " + mainPage.selectedIndex
        property int selectedIndex: -1
        head.sections.model: [ "first", "second", "third" ]
        head.sections.selectedIndex: mainPage.selectedIndex

        Rectangle {
            anchors.fill: parent
            color: "white"

            Label {
                anchors.centerIn: parent
                text: "Click me"
            }
        }

        MouseArea {
            anchors.fill: parent
            onClicked: mainPage.selectedIndex = (mainPage.selectedIndex + 1) % 3
        }
    }
}
