MVVM: Dropdown Value binding failing when DataSource is calculated field from ViewModel

[Jay]

Referencing this Fiddle.  Which is only a slight modification of this earlier question.

Overview:

• Select box is bound to a datasource from the viewmodel.  
• The datasource is dynamic (not static, but represented by a calculated field in the viewModel).

Expected Results:

• Select control contents are dynamically populated with data source via the ViewModel method.
• Selected Dropdown Value is bound to the appropriate viewModel field.

Actual Results:

• Dropdown box contents are dynamically populated with data source via the ViewModel method. - CHECK
• Binding to ViewModel for Dropdown

Hi, 

There are two problems in that code:

1. The dropDownList() function should be invoked.
2. You should wrap the result of the dropDownList in ObservableArray if you want to use it in other methods.

Here is the updated jsFiddle: http://jsfiddle.net/korchev/Lvsqu/4/
