ResourcesPopupCheckedListBoxControl lost binding

Hello,

I'm using ShedulerControl with ResourcesPopupCheckedListBoxControl for filtering resources.
But it works only once. If i update AppointmentStorage datasource, ResourcesPopupCheckedListBoxControl does not work anymore.

When my function Load() is called the first time ResourcesPopupCheckedListBoxControl works, if i call for a second time, the control lost binding and
i can't filter resources.

XAML
<dxsch:ResourcesPopupCheckedListBoxControl Name="filter" SchedulerControl="{Binding ElementName=scheduler}" Margin="89,0,0,0" MinHeight="25" HorizontalAlignment="Left" VerticalAlignment="Top" Width="200" />
