I've got a Grid with a cell that has an editor template that contains an auto complete object.
When the edit for this cell is complete, the grid displays the data as "[object Object]".
If the user goes back and uses the auto complete to select a field, the correct string is passed back to the Grid from the Editor template, however the auto complete functionality becomes buggy. (no javascript errors are thrown)
 Grid Code:
@(Html.Kendo().Grid<PendingBatchListingInput>()    .Name("PendingBatchListingInputGrid")    .Columns(c=>    {c.Bound(a => a.InputDebtorName).Title("Debtor").EditorTemplateName("InputDebtorName") //Shows valued of [object Object] the first time it is edited, shows correct value if user goes back to edit cell again})    .DataSource(ds => ds.Ajax()    .Model(m =>    {        m.Id(p =>p.InputId);             })    .Create(create => create.Action("PendingBatchListingInputCreate", "PendingBatchListing"))    .Update(update => update.Action("PendingBatchListingInputUpdate", "PendingBatchListing"))    .Read(r => r.Action("PendingBatchListingInputRead", "PendingBatchListing")        .Data("getData")        .Type(HttpVerbs.Post))        .ServerOperation(false)    ).Editable(e=>e.Mode(GridEditMode.InCell)))Editor Template Code: 
@model object<script>    function onAdditionalDataDebtorSearch() {        $('#InputDebtorName').data("kendoAutoComplete").list.width(500);        return {            debtorName: $("#InputDebtorName").val(),            clientId: null        };    }</script>@(Html.Kendo().AutoCompleteFor(m=>m)    .HighlightFirst(true)    .Filter(FilterType.StartsWith)    .Height(500)    .Placeholder("Select Debtor")    .DataTextField("Name")    .DataSource(source =>    {        source.Read(read =>        {            read.Action("ReadDebtorSearch", "PendingBatchListing")                .Data("onAdditionalDataDebtorSearch");        })        .ServerFiltering(true);    }).MinLength(5)    .Template(        "<span>" +            "#=data.Name#  | #=data.City#, #=data.State#" +        "</span>"    ))
