I have a table using Outsystems Data Grid.  I want users to be able to select rows from that table to import into the system.  I have a bool that indicates if it should be imported and I'm using a checkbox column to track that bool.  When they check the checkbox it doesn't save the data and I can't see the changes.  I then added in the logic that when they check it it uses the "SetCellData", however when I try to save it after it's still not saved.  There is nothing in the "GetChangedLanes" or any other place I can find.  Can someone show me what I'm doing wrong or share a file with this logic working properly?  

I appreciate the help.  I understand I'm probably missing something basic, but I can't for the life of me see it.  Thanks so much!
