Drill down Ajax style in knockout js
===

I am building a web app and am looking to convert the UI to use Knockout JS.  I am a total noob in Knockout so please be kind!

Normally I would load an employee list (using PHP) and then if an employee is selected I would find the ID of that employee using JQuery and then make and AJAX call to my backend, fill in the result box and slide it down.

Is there a way to replicate this behavior in Knockout?
