ajax，显示数据但在使用搜索时找不到它

Question

I'm using the code below to show countries and when select any country I will get the regions of this country, for now all work fine, but when I get the regions and using the search in the div can't get它因为 div 是空的，但是如果我选择任何区域，我会得到它的 id 警报，那么如何选择和搜索区域，请看屏幕截图https://imgur.com/VbHZOFK 我使用 jQuery Plugin For Bootstrap Select with Search – BootstrapSelect 链接https://www.codehim.com/others/jquery-plugin-for-bootstrap-select-with-search-bootstrapselect/ 我不知道如何找到搜索 jquery 代码，因为它位于 jquery 文件中的某个位置（文件和代码太多）

阿贾克斯：

    $(document).on('click','#countrylist li', function(){

        $.ajax({
            url:'/getRegions',
            type: 'GET',
            data: 'country_id='+$(this).data('value'),
            beforeSend: function( xhr )
            {

                Command: toastr["info"]("Uploading Data.....", "Processing")
            },

            statusCode: {
                422: function( result) {
                    console.log(result);
                    $('#error').html(result.responseText);
                    $('#static').modal('show');
                }
            },
            success: function(data){
                toastr.clear();

                var select = $('#regionlist');
                $('#regionlist').html('');
                select.empty(); 

     $(document).on('click', '#regionlist li', function(e) {
   alert($(this).data('value'));
     });

        $.each(data, function(index,element) {
                    select.append("<li data-filter='"+ element.name +"' data-value='"+ element.id +"'>" + element.name + "</li>");
                });
            },
            error:function(data){
            }
        });

    });

我在这里找到了解决方案： 成功的jQuery：

  $("#regionlistresult").html(data.regionlist);

在控制器中：

    public function getRegions(Request $request)
  {

 $region=Region::getRegionsByCountryID($request->input('country_id'));

   $regionlist = view("include.regionlist",compact('region'))->render();

   return response()->json([
  'regionlist' => $regionlist
 ]);
