Oddly, this works
$.post(url, $('form').serialize(), function (data) {
var z = $('main > section').empty(),
h = $('<div/>').html(data),
x = $('body').append(h).find($('div section'))
z.append(x);
h.remove();
})
Meanwhile, you might want to remove this line
$('[name="bio_submit"]').click()
since it fires automatically every time the DOM loads that `section`.
