Kendo MVC Grid paging buttons not changing results displayed - asp.net-mvc

Question

I have a Kendo Grid. The paging numbers are ok, items per page is ok, but when I press on page number the results in grid isn't changing, all results are shown in first page. Please help here.
Below is my code:
<script>
$(function() {
$("#invoices-grid").kendoGrid({
dataSource: {
data: #Html.Raw(JsonConvert.SerializeObject(Model.Invoices)),
schema: {
model: {
fields: {
JobNumber: { type: "string" },
CustomerName: { type: "string" },
DepartmentName: { type: "string" },
DateInvoice: { type: "string" },
ValidDays: { type: "number" },
Delivery: { type: "string" },
IsPayed: { type: "boolean" },
Payed: { type: "number" },
Status: { type: "boolean" },
}
}
},
#*type: "json",

},
},
schema: {

display_kendoui_grid_error(e);
// Cancel the changes
this.cancelChanges();
},

Currently server operations are enabled...
serverPaging: true,
serverFiltering: true,
serverSorting: true
... but the transport configuration is commented out. This is the cause of the problem.
If you want to use server operations, then configure the dataSource transport. Otherwise, use local data binding and disable server operations, as in this example:
