Horizontal scrolling doesn't work for ListBox in wpf

I tried to use this template for my listbox but when I use mouse wheel, horizontal scrolling doesn't work and I don't know why!

<ControlTemplate x:Key="ListBoxControlTemplate" TargetType="{x:Type ListBox}"><Border x:Name="Bd" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" Padding="1" SnapsToDevicePixels="True" ScrollViewer.CanContentScroll="True" ScrollViewer.HorizontalScrollBarVisibility="Visible" ScrollViewer.VerticalScrollBarVisibility="Disabled"><ScrollViewer Focusable="True" Padding="{TemplateBinding Padding}" Template="{DynamicResource ScrollViewerTargeting}" CanContentScroll="True" VerticalContentAlignment="Top" HorizontalScrollBarVisibility="Visible"><ItemsPresenter SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" ScrollViewer.CanContentScroll="True" ScrollViewer.VerticalScrollBarVisibility="Disabled" ScrollViewer.HorizontalScrollBarVisibility="Auto"/></ScrollViewer></Border><ControlTemplate.Triggers><Trigger Property="IsEnabled" Value="False"><Setter Property="Background" TargetName="Bd" Value="{x:Null}"/><Setter Property="BorderBrush" TargetName="Bd" Value="{x:Null}"/></Trigger></ControlTemplate.Triggers></ControlTemplate><ControlTemplate x:Key="ScrollViewerTargeting" TargetType="{x:Type ScrollViewer}"><Grid x:Name="Grid" Background="{TemplateBinding Background}"><Grid.ColumnDefinitions><ColumnDefinition Width="*"/><ColumnDefinition Width="Auto"/></Grid.ColumnDefinitions><Grid.RowDefinitions><RowDefinition Height="*"/><RowDefinition Height="Auto"/></Grid.RowDefinitions><Rectangle x:Name="Corner" Grid.Column="1" Fill="{DynamicResource {x:Static SystemColors.ControlBrushKey}}" Grid.Row="1" ScrollViewer.CanContentScroll="True"/><ScrollContentPresenter x:Name="PART_ScrollContentPresenter" CanContentScroll="{TemplateBinding CanContentScroll}" CanHorizontallyScroll="True" CanVerticallyScroll="False" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" Grid.Column="0" Margin="{TemplateBinding Padding}" Grid.Row="0" ScrollViewer.VerticalScrollBarVisibility="Disabled" ScrollViewer.HorizontalScrollBarVisibility="Auto"/><ScrollBar x:Name="PART_VerticalScrollBar" Template="{DynamicResource ComboBoxScrollBarControlTemplate}" AutomationProperties.AutomationId="VerticalScrollBar" Cursor="Arrow" Grid.Column="1" Maximum="{TemplateBinding ScrollableHeight}" Minimum="0" Grid.Row="0" Visibility="{TemplateBinding ComputedVerticalScrollBarVisibility}" Value="{Binding VerticalOffset, Mode=OneWay, RelativeSource={RelativeSource TemplatedParent}}" ViewportSize="{TemplateBinding ViewportHeight}" ScrollViewer.VerticalScrollBarVisibility="Disabled" ScrollViewer.HorizontalScrollBarVisibility="Auto"/><ScrollBar x:Name="PART_HorizontalScrollBar" Margin="200,0,200,20" AutomationProperties.AutomationId="HorizontalScrollBar" Cursor="Arrow" Grid.Column="0"
