МОФ CheckBox командования в DataTemplate

Question

У меня есть DataTemplate, как это:

<DataTemplate x:Key="CheckBoxDataTemplate"> 
    <CheckBox IsChecked="{Binding 
       Path=IsSelected, Mode=TwoWay}" 
       HorizontalAlignment="Center" 
       VerticalAlignment="Center" Name="aDM_LEVEL_FIELDListView" Path="SelectedItem"> 
     <i:Interaction.Triggers> 
      <i:EventTrigger EventName="Checked"> 
       <WPFCtlr:EventToCommand Command="{Binding DataContext.UnCheckCommand, RelativeSource={RelativeSource FindAncestor,ListView,1}}" CommandParameter="{Binding ElementName=_thisChk}" /> 
       <!--<i:InvokeCommandAction Command="{Binding Path=SelectItemRelayCommand}" />--> 
      </i:EventTrigger> 
     </i:Interaction.Triggers> 
    </CheckBox> 
    <!--Command="{Binding Path=DataContext.UnCheckCommand}" 
       CommandParameter="{Binding Path=IsChecked, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}" />--> 
</DataTemplate> 

Это templateSelector:

<TemplateSelector:PropertyDataTemplateSelector x:Key="templateSelector" 
     BooleanDataTemplate="{StaticResource CheckBoxDataTemplate}" 
     IsEnum="IsExclusive"/> 

И это ListView где упоминается шаблон:

<ListView Grid.Row="1" 
    ItemsSource="{Binding Path=FilteredLevelFields}" 
    Margin="5,10,5,5" 
    Name="aDM_LEVEL_FIELDListView" 
    SelectionMode="Single" 
    FontSize="13" 
    Background="AliceBlue" 
    BorderBrush="AliceBlue" 
    SelectedItem="{Binding Path=CurrentElement}"> 

    <!--Style of items--> 
     <ListView.ItemContainerStyle> 
      <Style TargetType="{x:Type ListViewItem}"> 
       <!--Properties--> 
       <Setter Property="Control.HorizontalContentAlignment" Value="Stretch" /> 
       <Setter Property="Control.VerticalContentAlignment" Value="Center" /> 
       <!--Trigger--> 
       <Style.Triggers> 
        <Trigger Property="IsSelected" Value="True"> 
         <Setter Property="Background" Value="{x:Null}" /> 
         <Setter Property="BorderBrush" Value="{x:Null}" /> 
        </Trigger> 
       </Style.Triggers> 
      </Style> 
     </ListView.ItemContainerStyle> 

     <ListView.View> 
      <GridView ColumnHeaderContainerStyle="{StaticResource GridViewColumnHiddenHeaderStyle}"> 
       <GridViewColumn Header="ID LEVEL FIELD" CellTemplate="{StaticResource FatherTemplate}" Width="300"/> 
       <GridViewColumn Header="Value" CellTemplateSelector="{StaticResource templateSelector}" Width="80" /> 
       <GridViewColumn Header="ID LEVEL FIELD" CellTemplate="{StaticResource DetailIdenTemplate}" Width="300"/> 
      </GridView> 
     </ListView.View> 
</ListView> 

Это моя команда в МоемМире:

RelayCommand _unCheckCommand; 
public ICommand UnCheckCommand 
{ 
    get 
    { 
     if (_unCheckCommand == null) 
     { 
      _unCheckCommand = new RelayCommand(
       param => this.UnCheck(param), 
       param => this.CanUnCheck 
      ); 
     } 
     return _unCheckCommand; 
    } 
} 

Моя цель - передать команду в качестве параметра элемент, который я выбираю в своем списке. Как мне это сделать?

я сам по себе:

<DataTemplate x:Key="CheckBoxDataTemplate"> 
    <CheckBox IsChecked="{Binding 
       Path=IsSelected, Mode=TwoWay}" 
       HorizontalAlignment="Center" 
       VerticalAlignment="Center" Name="aDM_LEVEL_FIELDListView" Path="SelectedItem" > 
     <i:Interaction.Triggers> 
      <i:EventTrigger EventName="Checked"> 
       <WPFCtlr:EventToCommand Command="{Binding DataContext.UnCheckCommand, RelativeSource={RelativeSource FindAncestor,ListView,1}}" CommandParameter="{Binding ElementName=aDM_LEVEL_FIELDListView, Path=SelectedItem}" /> 
       <!--<i:InvokeCommandAction Command="{Binding Path=SelectItemRelayCommand}" />--> 
      </i:EventTrigger> 
     </i:Interaction.Triggers> 
    </CheckBox> 
    <!--Command="{Binding Path=DataContext.UnCheckCommand}" 
       CommandParameter="{Binding Path=IsChecked, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type UserControl}}}" />--> 
</DataTemplate>
