That'll update the value of the cell.
You can't do what you're trying to do. You can't have a column with a
different dataField per row. The dataField for the column is the same for
every row.
Is this data coming from a database, through a view? You really should do this
there. You can set up a view column with an if/then that returns the column's
value you want.
