Kendo UI Child Grid -> Destroy Confirmation Firing Twice on Cancel - events

Question

I have a grid which has a child/sub Grid. It works fine, I can add and remove. However, when I attempt to run the command.destroy, should I press Cancel on the confirmation, it fires again (so I have to press Cancel again). If I choose Confirm, it doesn't popup again and does delete it on first try.
I am unsure whats causing this and I don't think it's my CSHTML but just need a second opinion.
#(Html.Kendo().Grid<ModelA>()
.Name("Grid")
.Columns(columns =>
{
columns.Bound(o => o.ID).Width(50);
columns.Bound(o => o.Name).Width(300);
columns.Bound(o => o.UpdateUser).Width(100);
columns.Bound(o => o.UpdateDate).Format("{0:d}").Width(100);
columns.Command(command => { command.Edit(); command.Destroy(); });
})
.ToolBar(toolbar => toolbar.Create())
.ClientDetailTemplateId("adTemplate")
.Pageable()
.Editable(editable => editable.Mode(GridEditMode.PopUp).TemplateName("RoleTemplate"))
.DataSource(dataSource => dataSource
.Ajax()
.Read(read => read.Action("RoleRead", "Role"))
.Update(update => update.Action("RoleUpdate", "Role"))
.Create(create => create.Action("RoleCreate", "Role"))
.Destroy(destroy => destroy.Action("RoleRemove", "Role"))
.PageSize(10)
.Model(model =>
{
model.Id(c => c.ID);
model.Field(c => c.UpdateUser).Editable(false).DefaultValue(Context.User.Identity.Name);
model.Field(c => c.UpdateDate).Editable(false).DefaultValue(DateTime.Now);
})
)
.Sortable()
.Filterable()
)

Update your version to the latest one. This was fixed some releases ago.
