如何将jQuery AJAX JSON对象从PHP渲染到KnockoutJS

Wondering if anyone can do a quick demo on Jsfiddle to show how it would work to do the following.

Let's say I have a mysql table with columns: product_name, product_price, product_id; I do a mysql select and return the array using an AJAX call. How do I render that on page using Knockout?

I can do the AJAX call and grab the data. It's returned as an object. I use json_encode in the PHP to return the data back in getJSON call.

What do I do next to render it? That's what I am stuck on. I just want to render a table looping product name, product id, and price.

    var allData = $.getJSON("ajax.php?request=getresults", data, function(response) {
        return (response);
    })

Thanks!
