Update Knockout.js Observable from JSON
I'm attempt to establish a grid and update it with more records via JSON. In this simple example I am able to achieve  the required functionality but I can only update / push one JSON record. I would like to be able to add multiple records via JSON? How could I achieve this? I assumed I might have to create some sort of for loop and push each JSON result to the observable but I was hoping that knockout might have a better way of updating / parsing via JSON? 

Heres a copy of what I have achieved so far: http://jsfiddle.net/sparkhill/crSbt/ 

         function Users(user_id, password) {
        this.user_id = ko.observable();
        this.password = ko.observable();
    }

    var viewModel = {

        users: ko.observableArray([]),
       

        addUser: function () {
            this.users.push({

                user_id: "",
                password: ""
            });
        },
        
        addJSON: function () {
            

            //Works Fine
            var JSONdataFromServer
            ='{"user_id":"frances","password":"password"}';

            //More than one result - wont map - Would Ideally like to map lots of records at one time
    //var JSONdataFromServer ='{"user_id":"frances","password":"password"}, {"user_id":"frances","password":"password"}';

            var dataFromServer = ko.utils.parseJson(JSONdataFromServer);


            this.users.push(dataFromServer);
            
             //Tried
            //this.users.push(JSON.parse(JSONdataFromServer));
            
   
        }
        
    };

    viewModel.users();
    ko.applyBindings(viewModel);

        </script>
