Knockout checkbox enable dependencies

[ivanov...@gmail.com]

I'm trying to make checkbox enabling with dependencies. 
I'd like to enable a checkbox if some of two input fields are not empty. 

and it works perfectly for initializing.. here is printscreen. But it doesn't work with changes, i mean that after you filling any of empty field it doesn't enable.

Here is this question on stackoverflow with code listings.

You must or use computed observable, or subscribe to changes. Your function not notify other model about change.

As I think:

1. You need contact class

2. In class Contact you need computed observable Is_Enabled

3. Get data from server and produce array of Contact elements

3. Do binding

4. Get fun.
