obj.onCellDataChanged = function(value){...};

Ok, How is this exactly used. The generic format [obj.something = function(value){...};] is almost useless as it is specified on almost every function and control in the documentation.

I want to be notified that a cell value has changed so that a method can pass the changed data back to the underlying controller layer.

I found the actual parameters:

obj.onCellValueChanged = function(value, col, row){ ... }

Where:
value is the new value contained in the cell
col is the column the changed happened in
row is the row the change happened in

This works with any of the embeded controls. A combo box will return the new selected value (not the text value, unless they are the same) or on check boxes, .true. or .false. bool values.
