how to load content from severak ActionNames Kendo UI

Question

HI ive't got a strange question:

 

We have a grid with vife tappages. Every tabpages loads corretly with the function "" .LoadContentFrom, exept the CustomerInvoices. It's not showing the last to columns.  This is probably because these 2 columns use another actionname in the controller. \

 

here is my KendoTabStrip

<div class="row">
    <div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">
        @(Html.Kendo().TabStrip()
              .Name("CustomerDetailsTabStrip")
              .Animation(false)
              .Items(tabstrip =>
              {
                  tabstrip.Add().Text("Diensten")
                      .Selected(_currentTab == 0)
                      .LoadContentFrom(Url.Action("CustomerServices", "Service", new { @id = Model.DebtorCode }));
                  tabstrip.Add().Text("Contractregels")
                      .Selected(_currentTab == 1)
                      .LoadContentFrom(Url.Action("CustomerContractLines", "ContractLine", new { @id = Model.DebtorCode }))
                      .Visible(!Authenticate.HasRight(Right.ManageGo));
                  tabstrip.Add().Text("Eenmalige kosten")
                      .Selected(_currentTab == 2)
                      .LoadContentFrom(Url.Action("CustomerCosts", "Cost", new { @id = Model.DebtorCode }))
                      .Visible(!Authenticate.HasRight(Right.ManageGo));
                  tabstrip.Add().Text("Facturen")
                      .Selected(_currentTab == 3)
                      .LoadContentFrom(Url.Action("CustomerInvoices", "Invoice", new { @id = Model.DebtorCode }))
                      .Visible(!Authenticate.HasRight(Right.ManageGo));
                  tabstrip.Add().Text("Locaties")
                      .Selected(_currentTab == 4)
                      .LoadContentFrom(Url.Action("CustomerLocations", "Location", new { @id = Model.DebtorCode }))
                      .Visible(!Authenticate.HasRight(Right.ManageGo));
                  tabstrip.Add().Text("Opmerkingen")
                        .Selected(_currentTab == 5)
                        .LoadContentFrom(Url.Action("Comments", "Comment", new { @id = Model.DebtorCode, commentType = "1" }));
                  tabstrip.Add().Text("Orders")
                    .Selected(_currentTab == 6)
                    .LoadContentFrom(Url.Action("CustomerOrders", "Order", new { @id = Model.DebtorCode }))
                    .Visible(!Authenticate.HasRight(Right.ManageGo));

              })
        )

    </div>
</div>

 And here is the different grid with the two columns that are missing in the tabstrip. How can i fix this so it is solso showning the last two columns ?

 

<div class="row">
    <div class="col-lg-12 col-md-12 col-sm-12 col-xs-12">
        <div class="hidden bg-danger" id="errorMessage"></div>
        @(Html.Kendo().Grid<InvoiceGridItem>()
                    .HtmlAttributes(new { @class = "table-responsive" })
              .Name("Grid")
              .Columns(columns =>
              {
              columns
                .Bound(c => c.InvoiceNumber).ClientTemplate("#if (InvoiceNumber) {# <a href=\"" + Url.Action("Details") + "/#=InvoiceNumber#\">#=InvoiceNumber#</a> #}#");
              columns
                  .Bound(c => c.InvoiceDate).Format("{0:d}");
              columns
                  .Bound(c => c.CustomerDebtorCode).ClientTemplate("<a href=\"" + Url.Action("Details", "Customer") + "/#=CustomerDebtorCode#\">#=CustomerDebtorCode#</a>");
              columns

              columns.Template(@<text></text>).Title(string.Empty).ClientTemplate("<a href=\"" + Url.Action("PDF", "Invoice") + "/#=InvoiceNumber#\" class=\"glyphicon glyphicon-cloud-download\" target=\"_blank\" title=\"Factuur wordt getoond in nieuw venster/tabblad.\nOf klik met rechter muisknop en kies 'Opslaan als...'\"> </a>");
