property binding in a repeater

[sedi]

Hi,
I have an item with 12 text fields, laid out as a grid and produced with a repeater.
Now I want to make bindings to one property each (line 29). How can I do that elegantly?

I don't even know which words to use for a google search on this...
I can imagine it might be possible with some kind of list in the property section?

Here's a condensed code that should clarify what I mean:

import QtQuick 2.2
import QtQuick.Controls 1.1
 
Item {
 
    id: personButtonBasis
 
    property string data00Text: ""
    property string data01Text: ""
    property string data02Text: ""
    property string data03Text: ""
    property string data04Text: ""
    property string data05Text: ""
    property string data06Text: ""
    property string data07Text: ""
    property string data08Text: ""
    property string data09Text: ""
    property string data10Text: ""
    property string data11Text: ""
 
 
    Grid {
        id: dataTextGrid
        columns: 3
        Repeater {
            id: dataFieldRepeater
            model:12
            Text {
                text: ???????????
            }
        }
 
}

import QtQuick 2.2
import QtQuick.Controls 1.1

Item {

    id: personButtonBasis

    property string data00Text: ""
    property string data01Text: ""
    property string data02Text: ""
    property string data03Text: ""
    property string data04Text: ""
    property string data05Text: ""
    property string data06Text: ""
    property string data07Text: ""
    property string data08Text: ""
    property string data09Text: ""
    property string data10Text: ""
    property string data11Text: ""
	

    Grid {
        id: dataTextGrid
        columns: 3
        Repeater {
            id: dataFieldRepeater
            model:12
            Text {
                text: ???????????
            }
        }

}

I tried in vain to "compose" the property name as in this (non-working) example (located starting from line 29):

Binding {
                    target: personButtonBasis;
                    property: (index<10)? "data0%1Text".arg(index) : "data%1Text".arg(index)
                    value: text
                }

Binding {
                    target: personButtonBasis;
                    property: (index<10)? "data0%1Text".arg(index) : "data%1Text".arg(index)
                    value: text
                }

It might well be a very stupid question, as I am still very new to the QML world.
