Submit form on upload

[lesliepound]

There are times, when you want your user to upload only one file, in which case the extra "submit" button is redundant. Made attempts to submit form on upload in file_upload,js with
$("#gallery_dropzone").on("success", function () {
$('#location_upload').submit();
});
(can't do it in form as "update" button is dynamically created after form is read). Ideas?

Thanks - Every else working great.
