[jQuery] Sortable Help

[Dave Maharaj :: WidePixels.com]

I am sorting but the data being sent is in wrong format.
Response headers:
 
 
data =
entry[]=cf43c5caa5e&entry[]=1cb5758d6aa&entry[]=ee713a3034a&entry[]=d32cea34
83f
        
key =   entry_0[]
 
        
but it should be
entry[0]=cf43c5caa5e&entry[1]=1cb5758d6aa&entry[2]=ee713a3034a&entry[3]=d32c
ea3483f
 
script looks like
 
$("#sortable").sortable({
  update: function() {
   $.post('/manage/entries/order/', {
   data: $("#sortable").sortable("serialize"),
   key: 'entry_0[]'
          });
      }
 });

Can someone point out where I went wrong?

Thanks
 
Dave
