Checking data at client side using Knockout & Binding Table

Question

Hi,
 
I am developing a web application for the firm using MVC & Knockout. I am very much new to MVC and Knockout. In the admin side I need to display the users who are applied, approved, rejected in the Grid format.
 
I wrote controller to get AllUsers and I can able to bind all those users to Table. And I want to filter them at the client side using knockout to reduce the round trips to DB. It will boost my application performance.
 
So, what I need is: how can I check whether the user is Approved or Rejected using Knockout and based on that check I need to bind that data to separate Tables.
 
I googled about this and I could able to understand properly as I am very much new to this Technology.
 
Can some body help me on this.
 
Thanks in advance
