You have 2 options:

change the TransactionMode to Automatic at the class attribute

[Transaction(TransactionMode.Automatic)]

open a transaction within your command

Transaction tr = new Transaction(commandData.Application.ActiveUIDocument.Document);
tr.Start("Command name here");

// your code

tr.Commit();
