Selected listview item within a grid not getting updated.

[Sneha]

I have a editable grid which has a list view in it. List view is getting populated properly but when i when i select a listview item within editable grid, All the fields get updated except the listview items.
Below is the code:

(function ($) {
    // UpdateAPI url
    var UPDATEUSER_API_URL = '/api/UserManagement/PostUpdateUser';
    // Create API url
    var CREATEUSER_API_URL = '/api/UserManagement/PostUpdateUser';
    // Delete API url
    var DELETEUSER_API_URL = '/api/UserManagement/DeleteUser';
    // Search API url
    var GETUSER_API_URL = '/api/UserManagement/GetUser';
    // Search By Id API url
    var GETUSERBYID_API_URL = '/api/UserManagement/GetUserById';
    // Get Role url
    var GETROLE_API_URL = '/api/RoleManagement/GetRole';

    var isCreating = false;

    $(function () {

        userSource =
            new kendo.data.DataSource({
                transport: {
                    read: {
                        url: GETUSER_API_URL,
                        dataType: "json"
                    },

                        if (operation == "destroy" && options.models.length > 0) {
                            return JSON.stringify(options.models[0]);
                        }
                        else if (operation !== "read" && options.models.length > 0) {

            });
        });
    }
})(jQuery);


Function written for binding the listview within the grid is marked in bold. While updating/creating any record, i am not able to insert/update the listview items in the database.
