Are you sure it's non-existing? The context in which that delegate is 
going to be created should have "index" injected into it.

Needless to say, all of this is deprecated in 5.15 (in favour of 
required properties), and even before you were never supposed to use 
unqualified properties like those. You were supposed to

1) always prefix them with model.
2) expose properties on the root of the delegate, use them internally as 
needed, and bind them when using the delegate in a view.
