ajax file upload and javascript

I'm trying to submit parameters and images to a servlet using valums / file-uploader uploader

The trouble my is Servlet receives no parameters on my first upload, and will sometimes receive parameters if i refresh the page. The Servlet always receives the file.

below is the javascript that handles the upload: (i script runs )

$(function(){
                var btnUpload=$('#upload');
                var status=$('#status');
                var txt=$('#SurveyTitle').val();
                        new AjaxUpload(btnUpload, {
                        action: '/NewUser/test',
                        data: { param1: txt },
                        name: 'uploadfile',
                        onSubmit: function(file, ext){
                                 if (! (ext && /^(jpg|png|jpeg|gif|wmv)$/.test(ext))){
                                        // extension is not allowed
                                        status.text('Only JPG, PNG or GIF files are allowed');
                                        return false;
                                }
                                status.text('Uploading...');
                        },
                        onComplete: function(file, response){
                                //On completion clear the status
                                status.text('');
                                var respo = response;
                                //alert(respo);
                                if(respo){
                                        $('<li></li>').appendTo('#files').html('<img   /><br />'+file).addClass('success');
                                } else{
                                        $('<li></li>').appendTo('#files').text(file).addClass('error');
                                }
                        }
                });

});

Have you used a tool such as Fiddler to see what is being sent to the server?
