Expected behavior If a checkbox column is added to a datatables control, more often than not is because some action needs to be performed on the selected rows. If the action changes the contents of the rows (e.g. delete the corresponding entries in a backend database), and the update method is called to refresh the contents of the datatables, the status of all checkboxes should be reset to "not checked", because the same rows now contain different data: if rows 3 and 4 were selected before the update, it does not make sense that rows 3 and 4 continue to be selected after the update, because if the update method has been called, it is because the contents have to be updated and it does not make sense to make the assumption that rows 3 and 4 are the only ones that have not been updated and therefore must continue to be selected. The same applies to a select control: if options 3 and 4 are selected, and the list of options is updated, it does not make sense for the "new" options 3 and 4 to be selected.

Actual behavior In a datatables control with a checkbox column, once a set of rows is selected (i.e. the checkboxes are checked), they remain selected even after the table is updated. The same happens to the checkboxes in a select control.
