Ok, call me an idiot.
It appears that with the placeholder "phdocumentmenus" when
recreating the dynamic controls on postback I was not recreating the
reference to the "click handler"
Now it functions.
For reference, Here is the snippet as it exists now from my page load
Dim lst As List(Of C1.Web.Command.C1WebMenu) = Session
("DocumentMenus")
If Not lst Is Nothing Then
phDocumentMenus.Controls.Clear()
For Each Menu As C1.Web.Command.C1WebMenu In lst
phDocumentMenus.Controls.Add(Menu)
AddHandler Menu.ItemClick, AddressOf FolderMenuClick
Next
End If
