While working with UI customization of Ajaxuploader using custom Queue table method as mentioned in Documentation (with ASP.NET and C#). 

Am facing strange problem when we use custom queue method as shown below 

var uploader=document.getElementById("<%=UploadAttachments1.ClientID %>");

uploader.handlequeueui=myqueueuihandler; 

Now when we use Javascript based UI customization Our .CS file events never get fired up, that event  gets  blocked. Due to which we are not able to save the files physically on our server. 

Basically we want our code control to come to below shown code event whenever a file is uploaded: 

    protected void UploaderAssets_FileUploaded(object sender, UploaderEventArgs args)

 Please  let us know the way to resolve it ASAP.
