com.google.gwt.event.shared.HandlerRegistration addDataChangedHandler(DataChangedHandler handler)
Examples of why data changed might be:
addData(), updateData(), or removeData() DataSource
updates from the server for ResultSet data (triggered by record editing, etc.) ResultSet data setData() doesn't call this notification directly, but it may fire if
one of the above listed events is triggered (e.g. a server fetch for ResultSet data).
Note that the operationType parameter is optional and will be passed and contain the operation (e.g.
"update") if this notification was triggered by a fetch, an addData(), updateData(), or removeData(), or a DataSource
update for ResultSet data (the first three reasons listed above) but otherwise will be
null.
