Trouble printing the '&" character.

I expect that following plugin should print "AB&D" but I get only "AB".
What am I missing regarding the '&" character ?

Thanks

import QtQuick 2.0
import MuseScore 1.0

MuseScore {
version: "2.0"
description: "This plugin adds Native American Flute Fingering Diagrams"
menuPath: "Plugins.Native American Flute"

onRun: {
var cursor = curScore.newCursor();
cursor.rewind(0);

var text = newElement(Element.STAFF_TEXT);
text.text = "";
text.text = text.text + "A";
text.text = text.text + "B";
text.text = text.text + "&";
text.text = text.text + "D";

text.pos.y=9
cursor.add(text);

Qt.quit();
} // end onRun
}
