How to get all results via output callback with TableSorter and Ajax pager

output_callback.param.js

output_callback : function(c, data, url) {
  var filename = $('#A3opts .output-filename').val();
  var newURL = url.replace(/page=[0-9]+/, 'page=0').replace(/size=[0-9]+/, 'size=10000000');
  if (c.originalSettings.widgetOptions.output_saveFileName == 'dynamic')
    filename = $('" . $this->table . "').find('caption').text().replace(/\s/g, '_') + '.csv';
  $('#csvForm #filename', top.$('#toolbar').contents()).val(filename);

  // remove filters for all rows
  if (c.widgetOptions.output_saveRows == 'a')
    newURL = newURL.replace(/&fcol(\[[0-9]+\])?=.+/g, '') + '&fcol';
  
  $.ajax({
    url: newURL
  }).done(function(data) {
    if (!data) {
      alert('Request had too much data, try to filter out some results and only export visible rows');
      console.log('Ajax must have timed out, results too large!');
      return false;
    }

    try {
      data = $.parseJSON(data);
    } catch(e) {
      alert('Something went wrong!');
      console.log('Ajax did not return proper JSON');
      console.log(e);
      return false;
    }

    var rows = c.widgetOptions.pager_ajaxProcessing(data, c.table);
    data = $.tablesorter.output.process(c, c.widgetOptions, rows['rows'], true);
    $('#csvForm #data', top.$('#toolbar').contents()).val(data);
    setTimeout(function() {
      $('#csvForm', top.$('#toolbar').contents()).submit();
      setTimeout(function() {
        $('#csvForm #filename', top.$('#toolbar').contents()).val('');
			  $('#csvForm #data', top.$('#toolbar').contents()).val('');
		  }, 250);
	  }, 250);
  });
} else {
  $('#csvForm #data', top.$('#toolbar').contents()).val(data);
  setTimeout(function() {
    $('#csvForm', top.$('#toolbar').contents()).submit();
    setTimeout(function() {
      $('#csvForm #filename', top.$('#toolbar').contents()).val('');
      $('#csvForm #data', top.$('#toolbar').contents()).val('');
     }, 250);
    }, 250);
  }
  
  return false;
