Submitting model with entities in MVC using DataTable fails when using pagination

I have uncommon issue today while trying to submit model with entities and using dataTable plugin.
Model was loosing entities data when user used pagination provided by dataTable plugin.

I post question on stackoverflow, unfortunately I did not get any answer but few hours later I found some small hack and it works now.

If anyone is interested I post it on stackoverflow:
