datatables, change results from SSI - datatables

Question

i use the SSI-Solution from the datatables-examples.
Now, i want to change and edit some results of the database (for example, i want to change a stored id throug an icon for this id etc.).
For the moment i have no idear at wich point i can catch the results and work with them. Maybe someone can explain it for me.
Here is the code if use for getting the database results
// DB table to use
$table = 'MODUL_1_CONTACTS';
// Table's primary key
$primaryKey = 'ACCOUNT_ID';
// Array of database columns which should be read and sent back to DataTables.
// The `db` parameter represents the column name in the database, while the `dt`
// parameter represents the DataTables column identifier. In this case simple
// indexes
$columns = array(
array( 'db' => 'CONTACT_GROUP', 'dt' => 0 ),
array( 'db' => 'KD_NO', 'dt' => 1 ),
array( 'db' => 'TYPE', 'dt' => 2 ),
array( 'db' => 'ORG_NAME', 'dt' => 3 ),
array( 'db' => 'VORNAME', 'dt' => 4 ),
array( 'db' => 'NAME', 'dt' => 5 )
);
/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
* If you just want to use the basic configuration for DataTables with PHP
* server-side, there is no need to edit below this line.

require( $vz.'assets/global/plugins/datatables/ssp.class.php' );
echo json_encode(
SSP::simple( $_GET, $table, $primaryKey, $columns )
);
Here is the JS Code
var table = $('#ajax_table1').DataTable( {
"processing": true,
"serverSide": true,
"ajax": $.fn.dataTable.pipeline( {
url: 'data.php',
pages: 5 // number of pages to cache
} ),
