如何在draggin后使用javascript显示警告？

Question

我有以下的javascript。代码的可拖动部分可以工作，但由于某种原因警报不起作用。有关如何修复它以获取警报的任何建议吗？

 <script src="http://twitter.github.io/bootstrap/assets/js/jquery.js"></script>

<%= javascript_include_tag "application" %>
<%= javascript_include_tag "jsapi" %>
<%= javascript_include_tag "jquery-1.3.2.min" %>
<%= javascript_include_tag "jquery-ui-1.7.1.custom.min" %>
   <script type="text/javascript">
  // When the document is ready set up our sortable with it's inherant function(s)
  $(document).ready(function() {

    $("#test-list").sortable({
      handle : '.handle',
      update : function () {
        var order = $('#test-list').sortable('serialize');
      }

    });
      });
  </script>
  <script>

   $(function(){
       $('#test1').on('click',function(){
          alert('test');
          // CONCATENATE TEXT
          // user = $('.user:nth-child(1)').text()+ ','+ $('.user:nth-child(2)').text();
          // alert(user);
          // $('#personalassessment_set3').val(user);
       });
   });

<input id="test1" type="button" value="Set Value" />
