datatable checkbox toggle column

I ve a huge datatable with too much column, i ve filtering some

    $(document).ready(function() {
var table = $('#example').DataTable( {
    "bJQueryUI": false,
    "bAutoWidth": false,
    "bDestroy": true,
  //  "bPaginate": false,
  //  "bInfo": false,
    "lengthMenu": [ [30, 40, 50, -1], [30, 40, 50, "All"] ],
"columnDefs": [
                   { "visible": false, "targets": [4] }, //OSversion
                   { "visible": false, "targets": [8] }, //VmVersions
                   { "visible": false, "targets": [7] }, //VMStates
                   { "visible": false, "targets": [6] }  //VMtoolsVersion
                 ], 
} );

$('input.toggle-vis').on( 'click', function (e) {
    e.preventDefault();

    // Get the column API object
    var column = table.column( $(this).attr('data-column') );

    // Toggle the visibility
    column.visible( ! column.visible() );
} );

} );

I want to add some checkbox to see which column i can add or remove, i ve try :

   $log .= '<div>   Toggle column: <table id="check1"><tr>';
                    my $j=0;
                    foreach $toogle (@logvmware) 
                    {
                        $log .= '<td><input type="checkbox" class="toggle-vis" data-column="'.$j.'"><FONT COLOR="#FF3333">'.$toogle.'</FONT></td>';
                        if ($j eq 6) {$log .= "<tr>";}
                        $j++;
                    }
                    $log .= '</table>   </div>';

My checkbox correctly add or remove column, but they re always empty !! I want them to be check if column is prompt and unchecked if column is hiding ...

I hope i was clear, i am not fluent english.

Thanks
