I'm using the block to remove an asset from my sortable div. The problem I'm running into, is when I refresh the sortable I also need it to trigger the ajax call to update the database based on the available list after the removal. How should I do this?

PHP Code:
 $("#all_assets").sortable({
                                
handle'p',
                                
cursor'move',
                                
update: function(eventdiv) {
                                $.
post(BASE_URL+"ajax/sort_ajax.php", { assets: $('#all_assets').sortable('serialize') } );
                                }
                            });


$(
'#asset_'+item[1]).fadeOut('fast', function(){
                    $(
this).remove();
                    $( 
"#all_assets" ).sortable"refresh" );
                
                })
