The reason is that those are context properties internal to the delegate. If
you want to expose some of the delegate's data you could bind them to a
property:
Component
{
id :myDelegate
Row {
property variant display : model.display
Text { height : 20; text : "Something" }
Text { height : 20; text : model.display }
}
}
