Get .subsubsub count of post per status queried using pre_get_posts

Ah! jQuery to the rescue!

function custom_admin_js() {

      global $get_all_statuses;  ?>

      <script type="text/javascript"> 
        jQuery(document).ready(function($) {
          //Bring my $get_all_statuses array and encode it for jquery 
          var myObjects = <?php echo json_encode($get_all_statuses);?>;

          //Run a each loop : jquery equivalent to php's foreach
          $.each(myObjects, function (index, value) {

            //console.log(index); //Status Label
            //console.log(index); //Status-name

            //count the WP list rows that has class names that matches your status name
            // For example: <div class="status-col status-col-Published">Published</div>
            var statct = $(".status-col-"+index).length,
                allct = $(".status-col").length; // Target the class that is unique to count all rows.

            //Update the value to the subsubsub element!
            $('.subsubsub li.'+value+' .count').html(statct);
            $('.subsubsub li.all .count').html(allct);

          });
        }); 
        </script>
    <?php
}
