ControlTemplate(Style) binding ItemsSource property - xaml

Question

I want to do a data binding in a Style(ControlTemplate) in a ListView
My ListView looks like:
<ListView ItemTemplateSelector="{StaticResource ItemTemplate_Selector}" ItemContainerStyleSelector="{StaticResource ItemContainerStyle_Selector}"/>
Most of properties fetched from ItemsSource are binding in the DataTemplate:
e.g.
<DataTemplate x:Key="OneOfItem">
<Grid>
<Grid.RowDefinitions>
<RowDefinition Height="30"/>
<RowDefinition Height="*"/>
</Grid.RowDefinitions>
<TextBlock Grid.Row="0" Text="{Binding Name}"/>
<StackPanel Grid.Row="1">
<RichTextBlock Grid.Column="0" local:HyperlinkExtensions.Text="{Binding Message}"/>
<TextBlock Grid.Column="1" Text="{Binding Time}"/>
</StackPanel>
</Grid>
</DataTemplate>
For the reason that there's a area that will be affected by different visual state and there's a property displayed in that area, so I have to binding it in the ItemContainerStyle like:
e.g.
<Style x:Key="HeadPicStyle" TargetType="ListViewItem">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="ListViewItem">
<Border>
<Grid>
<Grid.ColumnDefinitions>
<ColumnDefinition x:Name="Header" Width="20"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<Grid Grid.Column="0">
<TextBlock x:Name="HeaderText" Text="{Binding Header}"/>
</Grid>
<ContentPresenter Grid.Column="1" x:Name="contentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" ContentTransitions="{TemplateBinding ContentTransitions}" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}"/>
</Grid>
<VisualStateManager.VisualStateGroups>
<VisualStateGroup x:Name="AdaptiveStatesTest">
<VisualState x:Name="DefaultStateTest">
<VisualState.StateTriggers>
<AdaptiveTrigger MinWindowWidth="{StaticResource WideStateChangeThreshold}" />
</VisualState.StateTriggers>
</VisualState>
<VisualState x:Name="NarrowStateTest">
<VisualState.StateTriggers>
<AdaptiveTrigger MinWindowWidth="{StaticResource NarrowStateWindowWidth}" />
</VisualState.StateTriggers>
<VisualState.Setters>
<Setter Target="Header.Width" Value="100"/>
</VisualState.Setters>
</VisualState>
</VisualStateGroup>
</VisualStateManager.VisualStateGroups>
</Border>
</ControlTemplate>
</Setter.Value>
</Setter>
On my perspective, the itemContainerStyle is targeted to the itemSource in the ListView, so I can access it's property (means I can directly binding the property name)
However, the HeaderText's text can not be seen in the app.
I'm wondering if my binding in the style is wrong or not?
