fullcalendar获取上下月数据问题

Question

我在fullcalendar中添加了一个搜索功能，当我搜索后，再去点上月按钮，会同时发送搜索的请求，再点击下月或者今天按钮，就会把上次的搜索结果数据也显示在页面上，这是为什么？请问要怎么改？

js代码：
$(document).ready(function() {

    var initialLocaleCode = 'zh-cn';
    //$('#calendar').fullCalendar('removeEventSources');
    $('#calendar').fullCalendar({
        header: {
            left: 'prev,next today',
            center: 'title',
            right: 'month add edit'
        },
        defaultDate: moment(),
        locale: initialLocaleCode,
        buttonIcons: false, // show the prev/next text
        weekNumbers: true,
        navLinks: true, // can click day/week names to navigate views
        editable: true,
        eventLimit: true, // allow "more" link when too many events
        eventSources: [
           // your event source
          {
              url: '${ctx}${reqmap}calendar2',
              type: 'POST',
              data:function() { // a function that returns an object
                  return {
                        s_BTW_fdDateTime:
                            $('#calendar').fullCalendar('getDate').startOf('month').format("YYYY-MM-DD")+" 00:00~" + $('#calendar').fullCalendar('getDate').endOf('month').format("YYYY-MM-DD")+" 23:59"
                   };
                  
              },
              error: function() {
                  alert('there was an error while fetching events!');
              }
          }         
        ]
    });    
    
    //搜索按钮
    $("#btn").click(function(){
        var fdNames = $("#s_IN_fdNames").val();
        $("#calendar").fullCalendar('removeEvents');
        $("#calendar").fullCalendar('addEventSource', {
            url: '${ctx}${reqmap}findByGoodsNames',
          type: 'post',
          data: {
              s_BTW_fdDateTime: $('#calendar').fullCalendar('getDate').startOf('month').format("YYYY-MM-DD")+" 00:00~" + $('#calendar').fullCalendar('getDate').endOf('month').format("YYYY-MM-DD")+" 23:59",
            fdNames: JSON.stringify(fdNames)
          }
        });
      })
      // 刷新按钮
      $("#refresh").click(function(){
          window.location.reload();
      })
});

将$("#calendar").fullCalendar('removeEvents')改为$("#calendar").fullCalendar('removeEventSource');
