Datagrid Default Column Behavior

[Peter Haworth]

What is the correct way to set the default column behavior of a  
datagrid so that the script is entered for columns which have been  
customised to contain option menus?

I have set the default column behavior property for the datagrid but  
suing debug shows that the script is only executed for columns that  
hve not been customised in some way.

This is with LiveCode 4.5
