Atach event from static resource

Hi I have the follow code from resources (on App.xaml):

<Button x:Name="BaseWindow_Close" DockPanel.Dock="Right" 
                                                    VerticalAlignment="Center" Margin="5"
                                                    Height="20" Width="20" 
                                                    Style="{DynamicResource MetroWindowButtonStyle}"
                                                    Click="BaseWindow_Close_Click"></Button>

After, I call the resource on a window:

Style="{StaticResource WindowStyle}"

But I need that when I close the window, My custom button call the event from the resource file ...
