Datatables - jquery-datatables-checkboxes (gyrocode.com) checkboxes question

dinos_1974

Many thanks for reading.
This is for an open source project I created for a K12 school.
Please see the following:

http://users.sch.gr/chertour/projectsms/sms_list_ajax_demo.html

You will find:

1. Serverside Data fetched and embedded into a Datatable
2. The www.gyrocode.com plugin for enabling checkboxes ( jQuery DataTables Checkboxes )

I have enabled the first row as the checkboxes row.
When I click in a checkbox the rowID is printed in a <span> element.
Multiple checkboxes printed as expected.
When I press the Selectall checkbox the checkboxes are all selected but nothing is printed.
When I toggle (selectall checkbox UNSELECTED) then every value is printed.
It is supposed to be the other way around. Code is based on the tutorials and the examples.
I have tried numerous variations but to no avail.
Is there something I miss?
Any ideas or suggestions greatly appreciated.

For anyone interested the solution was given by the plugin author (www.gyrocode.com)

Please see below:

$(document).ready(function() {
   var table = $('#example').DataTable({
      'ajax': 'https://api.myjson.com/bins/1us28',
      'columnDefs': [
         {
            'targets': 0,
            'checkboxes': {
               'selectRow': true,
               'selectCallback': function(){
                  printSelectedRows();
               }
            }
         }
      ],
      'select': {
         'style': 'multi'
      },
      'order': [[1, 'asc']]
   });   
});

// Print selected rows
function printSelectedRows(){
   var rows_selected = $('#example').DataTable().column(0).checkboxes.selected();

   // Output form data to a console     
   $('#example-console-rows').text(rows_selected.join(","));
};
