How to clear the File List panel and upload file count on Upload Failure

Dear Team,

We are using CloudUpload Control and restricted the file size and type. On validation failed we are displaying an alert to the user. 

Is it possible to manually clear the File List Panel Items and Upload File Count using Javascript?  I tried to remove by using the below lines but count is not getting cleared. Please suggest.

  $('.rcuList > li').remove()
   $(".rcuFileList").find("ul").remove();

Thanks in advance

Phani.
