Kendo Grid JSON datasource binding - json

Question

I seem to be having an issue trying to bing my JSON result to my Kendo UI grid
This is my JSON result I get back from my web service:
"{
"Data":[{
"ModifiedBy":"Joe Blogs",
"ModifiedDate":"2015-04-27T00:00:00",
"Name":"One",
"Number":"201504260952",
"Status":"Draft",
"Id":3
},
{
"ModifiedBy":"Joe Blogs",
"ModifiedDate":"2015-07-08T11:04:00",
"Name":"fdasfdsa",
"Number":"20150708110209",
"Status":"Draft",
"Id":17},
{
"ModifiedBy":"Joe Blogs",
"ModifiedDate":"2015-07-09T08:44:00",
"Name":"Two",
"Number":"20150709084329",
"Status":"Draft",
"Id":20
}],
"Groups":null,
"Total":3
}"
This is my Grid and data source set up:
$(function () {
var myGrid = $("#myGrid");
myGrid.kendoGrid({
groupable: true,
sortable: true,
filterable: true,
pageable: {
refresh: true,
pageSizes: true,
buttonCount: 5
},
columns: [{
hidden: true,
field: "Id"
},
{
headerTemplate: ""
},
{
title: "Status",
field: "Status"
},
{
title: "Number",
field: "Number"
},
{
title: "Name",
field: "Name"
}]
});
var myDataSource = new kendo.data.DataSource({
transport: {
read: {
url: "/somewhere.svc/Data",
dataType: "json",
type: "GET"
}
},
schema: {
data: 'Data',
groups: 'Groups',
aggregates: 'Aggregates',
total: 'Total',
model: {
id: 'Id',
fields: {
Id: { type: 'number' },
Status: { type: 'string' },
Number: { type: 'string' },
Name: { type: 'string' },
ModifiedBy: { type: 'string' },
ModifiedDate: { type: 'date' }
}
}
},
pageSize: 5,
serverPaging: true,
serverGrouping: true,
serverSorting: true,
serverFiltering: true
});
myGrid.data("kendoGrid").setDataSource(myDataSource);
});
When the page loads I can see that I get the above JSON but I don't get any rows displayed in the grid.
What might I be doing wrong?
