Chosen updated not working

I have a chosen dropdown. I changed options content and call trigger chosen:updated but Chosen don't rebuild the dropdown. This is my updated

<select name="shortcode" style="width: 150px; display: none;" class="chosen_select chzn-done" id="select_shortcode">
   <option value=""></option> 
   <option value="7183">7183</option>
   <option value="7983">7983</option>
</select>

And this is Chosen dropdown (It should be rebuilt and removed two last <li> )

<ul class="chzn-results">
   <li id="select_shortcode_chzn_o_1" class="active-result" style="">7183</li>
   <li id="select_shortcode_chzn_o_2" class="active-result" style="">7983</li>
   <li id="select_shortcode_chzn_o_3" class="active-result" style="">8208</li>
   <li id="select_shortcode_chzn_o_4" class="active-result" style="">8308</li>
</ul>

This is my jQuery code:

$('#select_shortcode_mask').change(function(){
    var shortcode_mask = $('#select_shortcode_mask').val();
    $('#select_shortcode').empty();
    var shortcode = {"7X83":["7183","7983"],"8x08":["8208","8308"]};
    $('#select_shortcode').append("<option value=''></option>");
    if(jQuery.isArray(shortcode[shortcode_mask])){
            $.each( shortcode[shortcode_mask], function( subkey, subvalue ) {
                $('#select_shortcode').append("<option value='"+subvalue+"'>"+subvalue+"</option>");
            })
    } else {
        var full_shortcode = ["7183","7983","8208","8308"];
        if(jQuery.isArray(full_shortcode)){
            $.each(full_shortcode, function( subkey, subvalue ) {
                $('#select_shortcode').append("<option value='"+subvalue+"'>"+subvalue+"</option>");
            })
        }
    }
    $("#select_shortcode").trigger("chosen:updated");
});

SOLVED: I use older version so it should:

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

So dump ^^

I use chosen plugin frequently, of course I run into this issue more than once.

normally use .trigger("chosen:updated") can solve it. But just one minute ago, this method doesn't work any more, I feel so confused, cause I use a same function in 2 js file, let's say the a.js and b.js, it works in a.js, but not work in b.js. I can't figure out why... I almost lose my mind!!!

So, I check the api again.I found the .chosen("destroy") , inspired me!

And I think it's the Ultimate Solution: destroy it and rebuild it.

$('.chosen').chosen("destroy").chosen();

Am I too loud? :p
