SlickGrid on GitHub: https://github.com/mleibman/SlickGrid

Version One: SlickGrid example 4: Model
Version Two: SlickGrid example 3: Editing

For my website, I am using JQuery SlickGrid. I've been through both scripts so far and it has not been apparent how these scripts differ for what I am trying to accomplish. Version One uploaded to my server as everything I need, almost. I've implemented the undo button, however this is not functionable alike the Version Two uploaded to my server.

I need help to get the undo button to function on Version One.

Best Regards,
Tim
