ActionBar button not visible on sales order screen.

On sales order screen suppose so item is kit item then I wants to show kit details (child item) in popup 

In Non stock item we created one item with Is Kit field = true.

I added tool bar button

<px:PXToolBarButton Text="View Kit Details" CommandName="ViewKitDetails" PopupPanel="spKitDetails" />

It is visible on customization screen editor.

But not on screen.

Panel Details:

<px:PXSmartPanel ID="spKitDetails" runat="server" Width="600px" Height="400px" Caption="Kit Details">
		<px:PXFormView ID="formKitDetails" runat="server" DataSourceID="ds">
