odata not filling the kendo grid

[kenVic]

My code below does not populate the fields in the grid. I get an empty grid with headers only.
Fiddler shows that the read is executed and returning results. Any ideas?
$("#pageresultGrid").kendoGrid({
            dataSource: {
                type: "odata",
                schema: {
                    model: {
                        fields: {
                            DRG: { type: "string" },
                            DRGDescription: { type: "string" },
                        }
                    },

                    errors: function (response) {
                        return response.errors;
                    },
                    data: function (response) {
                        return response["value"];
                    }
                },
                transport: {
                    read: {
                        url: ksWebApiSearchUrl,
                        dataType: "jsonp"
                    }
                }
            },

            pageable: {
                numeric: true,

                refresh: true,

                pageSize: 5,

                previousNext: true,

                input: false,

                info: false,
                messages: {
                    display: "Viewing {0} - {1} of {2}",
                    empty: "No items to display",
                    page: "Page",
                    of: "of {0}",
                    itemsPerPage: "items per page",
                    first: "Go to the first page",
                    previous: "Go to the previous page",
                    next: "Go to the next page",
                    last: "Go to the last page",
                    refresh: "Refresh"
                }
            },
            sortable: true,
            columns: [
            {
                headerTemplate: '<input type="checkbox" id="checkAll">',
                template: '<input type="checkbox" value="1" id="results-select-row1"><label class="visuallyhidden" for="results-select-row1">Select Row</label>',
                width: 40
            },
            {
                field: "DRG",
                headerAttributes: {
                    "class": "ks-gridheader"
                },
                template: '<a href="javascript:GetTabDetail(#=DRG#)">#=DRG#</a>',
                width: 60,
                title: "DRG"
            },
            {
                field: "DRGDescription",
                headerAttributes: {
                    "class": "ks-gridheader"
                },
                width: 130,
                title: "DRG Description"
            }
            ]
        });

In the DataSource configuration you've overridden the data function which might be the cause of the issue. When you instruct the DataSource with type: "odata" it applies predefined settings in order to hide the complexity of supporting OData services.

You can find runnable example here: https://github.com/telerik/kendo-examples-asp-net/tree/master/grid-odata-crud
