Calculated field does not update when parent field is changed

[Russell]

I am using Kendo MVVM with a hierarchical view model. I have an array of items, and each has sub-items. I have a setting at the root level which determines what sub-item is selected for each item (based on its index).

All of my data binds correctly, but when I 'set' the selected item index at the root level, the calculated properties on the items are not getting updated.

The following code demonstrates the issue:

What is going on here?

Hi,

the parent().parent() approach does not build a dependency. Please check an alternative one.
