JQuery - 选择自动完成功能没有被调用？

Question

我有以下代码将自动完成添加到我的文本框，自动完成显示和一切正常，但是当用户选择一个项目选择回调不会被调用？ 任何解决方案？

$(function() { 

$("#txtItem").autocomplete({ 
    minLength: 1, 
    source: function (request, response) { 
     $.ajax({ 
      url: "/Correct url here", 
      dataType: "json", 
      data: { 
       term: request.term 
      }, 
      success: function (data) { 
       response($.map(data, function (item) { 
        return { 
         label: item.Name, 
         value: item.Name 
        } 
       })) 
      }, 
      select: function (event, ui) { 
       alert("sdfsdf"); 
       //$("#txtItemId").val(ui.item.value.ItemId); 
      } 
     }) 
    } 
}) 

}

重写代码是这样的：

$(function() { 

$("#txtItem").autocomplete({ 
    minLength: 1, 
    source: function (request, response) { 
     $.ajax({ 
      url: "/Correct url here", 
      dataType: "json", 
      data: { 
       term: request.term 
      }, 
      success: function (data) { 
       response($.map(data, function (item) { 
        return { 
         label: item.Name, 
         value: item.Name 
        } 
       })) 
      }    
     }) 
    }, 
    select: function (event, ui) { 
     alert("sdfsdf"); 
     //$("#txtItemId").val(ui.item.value.ItemId); 
    } 
}) 

}

    $.ajax({ 
     url: "/Correct url here", 
     dataType: "json", 
     data: { 
      term: request.term 
     }, 
     success: function (data) { 
      response($.map(data, function (item) { 
       return { 
        label: item.Name, 
        ItemId: item.ItemId//this is will put item id in memory 
       } 
      })) 
     }    
    }) 
},//this is after the source property select is an auto complete property many examples screw this up and it is in side the ajax block of code 
select: function (event, ui) { 
    alert("sdfsdf"); 
    //$("#txtItemId").val(ui.item.value.ItemId); 
    } 
    })}
