Android: Backspace dont erase selected text

The backspace key on the Android virtual keyboard doesn't erase the selected text.
It works well on Windows.

import QtQuick 2.2
import QtQuick.Window 2.1

Window {
visible: true
width: 1024
height: 768

TextInput

{ x: 423 y: 328 width: 200 height: 50 text: "Test" onActiveFocusChanged: selectAll() }

}
