Change binding value in custom template trigger - wpf

Question

How I can change binded property in custom template?
Button with Path Fill which is binded to Foreground of button:
<Button Style="{DynamicResource CustomButtonStyle}"Foreground="White" >
<Path Data="PATH_DATA" Stretch="Uniform" Fill="{Binding Foreground, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=Button}}" ></Path>
</Button>
Here is custom style with override template:
<Style x:Key="CustomButtonStyle" TargetType="{x:Type Button}">
<Setter Property="Background" Value="{x:Null}"/>
<Setter Property="BorderBrush" Value="White"/>
<Setter Property="BorderThickness" Value="0"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type Button}">
<Border x:Name="border" BorderBrush="{TemplateBinding BorderBrush}" BorderThickness="{TemplateBinding BorderThickness}" Background="{TemplateBinding Background}" SnapsToDevicePixels="True">
<ContentPresenter x:Name="contentPresenter" ContentTemplate="{TemplateBinding ContentTemplate}" Content="{TemplateBinding Content}" ContentStringFormat="{TemplateBinding ContentStringFormat}" Focusable="False" HorizontalAlignment="{TemplateBinding HorizontalContentAlignment}" Margin="{TemplateBinding Padding}" RecognizesAccessKey="True" SnapsToDevicePixels="{TemplateBinding SnapsToDevicePixels}" VerticalAlignment="{TemplateBinding VerticalContentAlignment}" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsMouseOver" Value="True">
<Setter Property="Foreground" Value="#d5113f"/>
</Trigger>
<Trigger Property="IsPressed" Value="True">
<Setter Property="Foreground" Value="#d5113f"/>
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
But changing Foregroud in trigger
<Setter Property="Foreground" Value="#d5113f"/>
will do nothing

Because you set Foreground to a fixed value, according to Dependency Property Setting Precedence List, your style trigger will not override this value. You need to bring Foreground set into Style as another setter like this:
<Style x:Key="CustomButtonStyle" TargetType="{x:Type Button}">
<Setter Property="Foreground" Value="White"/>
...
</Style>
