jquery events receive and stop not working on droppable lists -


the html formed , working correctly, neither alerts or functions firing; seems these aren't working. i'm stumped, because seems strange work stop:, nothing else.

i'm persisting order within tabs successfully, without these events firing, i'm not sure how persist moves across tabs without hacking.

$( ".connectedsortable" ).sortable({     opacity: 0.5,     placeholder: "ui-state-highlight",     stop: function( event, ui ) {          $('.connectedsortable').each(function() {             if($("#"+this.id).length > 0){                 var margin_id = $(this).attr('margin_id');                 var group_id = $(this).attr('group_id');                 var sortedids = $( "#"+this.id ).sortable( "toarray" );                 console.log(sortedids);                 update_widget_order(sortedids,__user_id,__page_id,margin_id,group_id);              }         });          // update widget order      },     receive: function( event, ui ) {         alert('test');         $('.connectedsortable').each(function() {             if($("#"+this.id).length > 0){                 var margin_id = $(this).attr('margin_id');                 var group_id = $(this).attr('group_id');                 var sortedids = $( "#"+this.id ).sortable( "toarray" );                 console.log(sortedids);                 update_widget_order(sortedids,__user_id,__page_id,margin_id,group_id);             }         });     }     ,     remove: function( event, ui ) {         alert('remove');         /*$('.connectedsortable').each(function() {             if($("#"+this.id).length > 0){                 var margin_id = $(this).attr('margin_id');                 var group_id = $(this).attr('group_id');                 var sortedids = $( "#"+this.id ).sortable( "toarray" );                 console.log(sortedids);                 update_widget_order(sortedids,__user_id,__page_id,margin_id,group_id);             }         });*/     }  }).disableselection();
