Default Filtervalue not send when bServerSide processing

[GoogleCodeExporter]

I have a datatable with serverSide processing. The data is loaded via AJAX.
I have a column with columnFilter type "select".
I set the selected property of this columnFilter, so this option gets the 
attribute "selected" in HTML.

When the dataTable executes the AJAX query my selected option is not set in the 
sSearch Array which is send to the server.
