Create a basic Grid using KnockoutJS Mapping plugin and MVC 3

    This answer gives the details of using the mapping plugin and mvc for doing the basic grid .

    As the request is done irregularly , The  $.getJSON want the user to transfer the  callback to deal with the result ,.

    So, Try this example code :

var viewModel = {};
$.getJSON('WeightTracker/List', function(result) {
    viewModel.stats = ko.mapping.fromJS(result.Data);
    ko.applyBindings(viewModel);
});

From the above consideration,Its is better to be  binding in the following way .

<tbody data-bind='template: {name: "statRowTemplate", foreach: stats }'></tbody>

The process is done with a JavaScript object and not a JSON string during doing the  $.getJSON
