The problem is most likely that you are using fromJSON when you really mean fromJS. $.getJSON will already create an object for you while ko.mapping.fromJSON reads in a JSON string. ko.mapping.fromJS reads in a Javascript Object.

See this JSFiddle for more: http://jsfiddle.net/hB3Rm/

Essentially, change this line:

Listing_ViewModel = ko.mapping.fromJSON(data);

to this line:

Listing_ViewModel = ko.mapping.fromJS(data);
