Multiple file upload in asp.net core using ajax on selection

Am new to asp.net core, I want to upload multiple files on user file selection with ajax in asp.net core. I use razor page with input file tag.

I follow each step of this article https://codepedia.info/ajax-file-upload-aspnet-core-razor-pages

I am able to call file selection event, but jquery ajax function not getting call, no debug on server side code hence no file upload. not single file upload. my code is not go in debug mode.

CODE

   $("#fileUpload").on('change', function () {

                var files = $('#fileUpload').prop("files");                
                var url = "/Index?handler=MyUploader";
                formData = new FormData();
                formData.append("MyUploader", files);              
               
                jQuery.ajax({
                    type: 'POST',
                    url: url,
                    data: formData,
                    cache: false,
                    contentType: false,
                    processData: false,
                    beforeSend: function (xhr) {
                        xhr.setRequestHeader("XSRF-TOKEN",
                            $('input:hidden[name="__RequestVerificationToken"]').val());
                    },
                    success: function (repo) {
                        if (repo.status == "success") {
                            alert("File : " + repo.filename + " is uploaded successfully");
                        }
                    },
                    error: function (data) {

                        console.log(data);
                    }
                });
            });
