jQuery file upload Resuming file uploads

Question

I am using the Jquery file upload basic-plus.html. I am not sure How to use the Resumable uploading functionality in the below code.

I see something like this according to the documentation but not sure How to use that with the basic-plus.html

$('#fileupload').fileupload({
    maxChunkSize: 10000000, // 10 MB
    add: function (e, data) {
        var that = this;
        $.getJSON('server/php/', {file: data.files[0].name}, function (result) {
            var file = result.file;
            data.uploadedBytes = file && file.size;
            $.blueimp.fileupload.prototype
                .options.add.call(that, e, data);
        });
    }
});

I tried something like below. But didn't work.

basic-plus.html

 $(function () {
        'use strict';
        // Change this to the location of your server-side upload handler:
        var url = window.location.hostname === 'blueimp.github.io' ?
                    '//jquery-file-upload.appspot.com/' : 'server/php/',
            uploadButton = $('<button/>')
                .addClass('btn btn-primary')
                .prop('disabled', true)
                .text('Processing...')
                .on('click', function () {

                    var $this = $(this),
                        data = $this.data();

                    $.getJSON('server/php/', {file: data.files[0].name}, function (result) {
                        console.log('come here');
                        console.log(result);
                        var file = result.file;
                        data.uploadedBytes = file && file.size;
                        //$.blueimp.fileupload.prototype.options.add.call($this, data);
                    });

                    $this
                        .off('click')
                        .text('Abort')
                        .on('click', function () {
                            $this.remove();
                            data.abort();
                        });
                    data.submit().always(function () {
                        $this.remove();
