Error trying to sync to remote datasource

[Devon]

I'm trying to sync changes to my remote datasource but it's only changing them locally. 

Here's my code:

Datasource:

var dataSource = new kendo.data.DataSource({

            transport: {

                read: {

                    url: "http://localhost:8080/databases/shipping/docs",

                    dataType: "json",

                    data: {

                        q: "javascript"

                    }

                },

                update: {

                    url: "http://localhost:8080/databases/shipping/docs",

                    dataType: "json"

                }

            },

            schema: {

                model: {

                    id: "id",

                    fields: {

                        Name: { type: "string" },

                        Telephone: { type: "string" },

                        Address: { type: "string" },

                        Suburb: { type: "string" },

                        City: { type: "string" },

                        Province: { type: "string" },

                        Country: { type: "string" },

                        PostalCode: { type: "string" },

                        DeliveryStatus: { type: "string" },

                        Packages: { type: "auto" }

                    }

                }

            }

        });

"Save Changes" Button Click: It might be a bit messy because I've been trying loads of different techniques

var packageId;

 

        function saveChanges(e) {

            var button = e.button,

                item = packageDataSource.get(button.data("itemId"));

            packageId = item.ID;

             

            dataSource.fetch(function () {

                var packageToUpdate = dataSource.data()[id].Packages[packageId];

                packageToUpdate.Status = "Delivered";

                dataSource.sync();

                console.log(dataSource);

            });

        }

I can see the changes reflecting in my console when I check the console.log(dataSource); after the dataSource.sync(); but when I check my remote database there's no change.

Have you confirmed that a request is sent?
Can you post it here? 
Have you checked your server logs?

I can't see any record of the request being sent. 

When I request the data from the database initially I can see the request in fiddler but not when I try sync.

Can you post a JSFiddle example of the problem?

Unfortunately I have no experience with jsfiddle so I'm struggling to adapt my code to it. 

I have attached a copy of my code here for you. Will that help??
