responsive-resize.dt problem

chilek

I have a table with 9 columns and own custom header row.
I try to attach my code to responsive-resize.dt event the following way:

  $('#my-table').on('responsive-resize.dt', function (e, datatable, columns) {
    console.log(e);
    console.log(datatable);
    console.log(columns);
  }).DataTable({
    details: {
      display: $.fn.dataTable.Responsive.display.childRowImmediate,
      type: ''
    }
  });

For first event handler I get something as follows for column parameter (after initial page load):
[true, "-", "-", "-", "-", "-", "-", "-", "-"]

All next event handlers get:
[true, true, true, true, true, true, true, true, false]

Output for first call is always the same - I mean it does not depend on web browser window size - even if browser have very small width the output doesn't change.
All subsequent event handlers show true column visibiliy state.

Am I doing wrong something or it's a bug?
