[Qt-qml] Element at 'index' in Column or Row

It would probably work in this case, but it's very bad style to use the children 
property, for anything really. This is because QML may add whatever children
it feels like, so there's no guarantee that the repeater's first delegate instance
is forever its child at index 0.

Rakesh, the proper way of doing what you want is to define a ListModel for 
your repeater and give its ListElements a property that you bind to the Text
element's text property. Then to change the text of a particular repeater delegate
just change the corresponding ListElement's property.

See
http://doc.qt.nokia.com/4.7-snapshot/qml-listmodel.html#setProperty-method
(and http://bugreports.qt.nokia.com/browse/QTBUG-10458)

I'm fairly sure testcolumn.children[5].text = "foo" should do it.
