This happens in Jquery and happens ONLY when the first option is empty. You can check it at your example with the id "#form_field" . If you do a simple

$('#form_field').val('');

and then trigger the chosen select:

$("#form_field").trigger("liszt:updated");

everything works fine. The triggers is working as we expected the only thing that didn't work is to make disappear the x (or else clear) button.
