Binding View Model property in Style in user Control in WPF - wpf

Question

I have an exceed data grid and I want to bind context menu property of column header.
Here is my code
<UserControl
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:xcdg="http://schemas.xceed.com/wpf/xaml/datagrid" x:Class="Sedan.Ux.Sheets.Views.SheetView"
mc:Ignorable="d"
d:DesignHeight="300" d:DesignWidth="300">
<UserControl.Resources>
<BooleanToVisibilityConverter x:Key="VisibilityConverter"/>
<Style TargetType="{x:Type xcdg:ColumnManagerCell}">
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="{x:Type xcdg:ColumnManagerCell}">
<Grid VerticalAlignment="Center" HorizontalAlignment="Stretch">
<Grid.ColumnDefinitions>
<ColumnDefinition Width="*"/>
<ColumnDefinition Width="*"/>
</Grid.ColumnDefinitions>
<TextBlock Grid.Column="0" Text="{TemplateBinding Content}" HorizontalAlignment="Stretch"/>
<TextBlock Grid.Column="1" Text=" ▼" HorizontalAlignment="Stretch" >
</TextBlock>
</Grid>
</ControlTemplate>
</Setter.Value>
</Setter>
<Setter Property="ContextMenu">
<Setter.Value>
<ContextMenu DataContext="{Binding Menus}" ItemsSource="{Binding Menus}">
<ContextMenu.ItemContainerStyle>
<Style TargetType="MenuItem">
<Setter Property="Header" Value="{Binding Name}"/>
<Setter Property="ItemsSource" Value="{Binding SubMenus}"/>
<Setter Property="Command" Value="{Binding Command}"/>
<Setter Property="CommandParameter" Value="{Binding Name}"></Setter>
</Style>
</ContextMenu.ItemContainerStyle>
</ContextMenu>
</Setter.Value>
</Setter>
</Style>
</UserControl.Resources>
<Grid>
<xcdg:DataGridControl Grid.Row="0" x:Name="Sheet" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="3" AutoCreateColumns="True" ReadOnly="{Binding ReadOnly}" ItemsSource="{Binding Data}" SelectionMode="Single" SelectedItem="{Binding SelectedItem}">
</xcdg:DataGridControl>
</Grid>
</UserControl>
I am not able to bind Menus property when I am using Setter in style.
If I remove the binding and hard code menu items ,I am able to see the context menu.
I have done research on how to get it done and I found various suggestions on stackoverflow and other forums regarding using 'Relative Source Self' in binding but that didnt work for me.
If I bind Menus to context menu of any button in user control (not via style) , then I am able to see menu.
Please help.
