Disabling check boxes in a group dynamically

[Raj Kris]

A group of check boxes are dynamically generated based on a web service.

Upon checking a box should disable/enable few check boxes, this too comes from the service 

ex: 

CategoryID: 1, CategoryDesc: One, InActiveIDs:{2,4},

CategoryID: 2, CategoryDesc: Two, InActiveIDs:{1,3},

CategoryID: 3, CategoryDesc: Three, InactiveIDs:{2,1}

How do I achieve this using knockout?

Thank you

Regards
