Don´t see template-upload with add : jqueryfileupload config

Question

Why can't I see the template-upload when I use add: in the fileUpload config

It doesn't work when add the option add: function(){}

$('#formpublicacion').fileupload({
	dataType: 'json',
	url: 'publicaciones/',
	add: function (e, data){
	$("#publicar").on('click', function () {
       data.submit();
   	});
  },
});

Answer 1

I replaced by this code

$('#fileupload').fileupload({
    dataType: 'json',
    add: function (e, data) {
        var that = this;
      //add this line
	    $.blueimp.fileupload.prototype.options.add.call(that, e, data);
        $("#up_btn").on('click', function () {
            data.submit();
        });
    },
});
