Get clicked MenuItem header value from datagrid context menu in WPF/PowerShell

In a WPF DataGrid via PowerShell, I have added a context menu and MenuItems from an Array. I would like to get the header value of clicked MenuItem to handle the click event further. I had tried add_Click event to the MenuItem object but it does return any value. I'm looking for some ideas to get the Header value in this scenario (or) if there is any different better approach to achieve this goal. Thanks in advance.

[xml]$inputXML=@"
<Window
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

<Window.InputBindings>
        <KeyBinding x:Name="keyTest" Modifiers="Control" Key="N" Command="{Binding CreateCustomerCommand}" />
</Window.InputBindings>

<Grid>
    <DataGrid x:Name="dg" Margin="5,5,0,0" Height="250" Width="350" ColumnWidth="Auto" AlternationCount="1" IsReadOnly="True" SelectionMode="Extended" SelectionUnit="Cell" Background="White" ClipboardCopyMode="IncludeHeader" > 
        <DataGrid.ContextMenu >

            $cxMenu.Items.Add($cxMenuitem.Header)

You should be able to cast $args[0] to a MenuItem and access its Header property directly:

$cxMenuitem.Add_Click({    
    $sender = [System.Windows.Controls.MenuItem]$args[0]
    # Use $sender.Header ...
})
