ChildRows of related Tabel

KennethWinther

Hello everybody
I've followed this example: https://datatables.net/examples/api/row_details.html.
I've used it in my MVC5 ASP .NET App With EntiyFrameWork DataBase first and it worked fine
Except for one thing.
My problem is, how do I fill the child rows with the related data to my main table.
The example just fills child row with data from one table.
I need the child rows to be exactly that - a result of the parent table.
So when I have a 1-* (1 Service - many ServiceTexts). I get all the data just fine when I Query the model.
But the table

 function format(d) {
                // `d` is the original data object for the row
                return '<table cellpadding="5" cellspacing="0" border="1" style="padding-left:50px;">' +
                    '<tr>' +
                    '<td>Dags dato:</td>' +
                    '<td>' + d.Dagsdato + '</td>' +
                    
                    '<td>Udført af:</td>' +
                    '<td>' + d.udføresaf + '</td>' +
                                      
                    '<td>Tid:</td>' +
                    '<td>' + d.Tid + '</td>' +
                    
                    '<td>Tidsforbrug:</td>' +
                    '<td>' + d.Tidsforbrug + '</td>' +
                                       
                    '<td>Part SN:</td>' +
                    '<td>' + d.itemID + '</td>' +
                    
                                        
                    
                    '<td>Text:</td>' +
                    '<td>' + d.Text + '</td>' +
                    
                    
                    '<td>ServiceID:</td>' +
                    '<td>' + d.ServiceID + '</td>' +
                    '</tr>'                   
                    '</table>';
            }

returns Undefined. I don't understand how the table would know what d is and if i only have to replace d with something
for this to work.
Can anyone help? This is driving me crazy.

EDIT:
I think the problem lies here somewhere in the lower part where:
// Add event listener for opening and closing details.
Seems like this is not beeing used or returning nothing.
The Ajax option url:home/GetService works fine for the DataTable.
So i states this for the GET pat of the small table aswell.
Is this wrong?

           $(document).ready(function () {
                var table = $('#myDatatable').DataTable({
                    "ajax":
                    {
                        "url": '/home/GetService',
                        "type": "GET",
                        "datatype": "json"
                    },
