I want swap two element in the sortable container with click event, but I cant do this.

<http://jsfiddle.net/prince4prodigy/rvfYE/>

```
$( "#sortable" ).sortable();
$( "#sortable" ).disableSelection();
$('#click').bind('click', function(){
    $('#li-3').animate({index:0},500);
    $('#li-1').animate({index:2},500);
});

```
