Display “Display name” instead of field name in WPF DataGrid

Question

          
This is my Class definition.
  
 public class Customer { 

[Display(Name="Customer ID")]
 public int ID { get; set; }
 [Display(Name="Customer Name")]
 public string CusName { get; set; } 
}
  
This is my XAML code
  
<DataGrid Name="DataGrid" />
  
And this is data binding
  
 public Test() { 
InitializeComponent();
 List<Customer> cus = new List<Customer>();    
     cus.Add(new Customer() { ID = 1, CusName = "Jackson" });    
     cus.Add(new Customer() { ID = 2, CusName = "Micheal" });  
     cus.Add(new Customer() { ID = 3, CusName = "Jackson" });
     DataGrid.ItemsSource = cus; 
}
  
This is the result:
  
  
The DataGrid header columns diplay the ID,CusName, they are Customer's field name.
  
How to make DataGrid header column display Customer ID, Customer Name  instead of ID, CusNumber ? They are in [Display] attribute
