Options binding does not initial select or update selected
I have a data structure that I try to data bind to a options drop-down, the drop-down data and the selected item data for each parent item are not shared since they came from two different ajax requests (i.e references are no the same). To fix this I thought that I should use the optionsValue binding to tell it which property to use to match selected item, but it does not work. 

It does not initial select any item, and it does not update selected item when selected from view. Please see fiddle for live code example
