jQuery .get() and Perl not functioning together

I'm having a little trouble with something simple I think. I've got a Perl script that already contains a bunch of functioning JQuery. I was hoping to use .blur and .get to run an email validation sub in Perl immediately when the user leaves the email address field. However, I can't seem to connect a Perl script and the JQuery call together. So I've simplified as much as I can just to try to get it to function. Basically, the user leaves the input field, the script is called, simply prints something and I have Jquery through an alert.

JQuery

$('#billemail').blur(function() {
    $.get('ajax_email_check.pl', { 'email': $('#billemail').val() }, function(data) {
        alert ("Billing email is "+data+"!");
    });
});

Perl

#!/usr/bin/perl

use warnings;
use DBI;
use CGI;
use CGI::Carp qw(fatalsToBrowser);
require "./lib/servervars.pl";
require "./lib/common.pl";

my $email_address = param('email');

#my $email_valid = &check_email($email_address);

#if ($email_valid) {
#    $output = "Success";
#} 
#else {
#    $output = "Fail";
#}

print "Success";

Of course if I remove the .get line and closing tags, the alert is triggered upon the field losing focus. Thanks for the help!

Your Perl script (at least the version you've posted) doesn't output a content type header. That's the very least a CGI script must output: the response headers, an empty line signalling the end of the headers, and optionally the content (the string success in your case), e.g.

print "Content-Type: text/plain\n\n";
if (email_is_valid()) {
  print "success";
} else {
  print "error";
}

Why have you escaped the $ here?

$.get('ajax_email_check.pl', { 'email': \$('#billemail').val() }

                                       ^^^^^

At the very least that'll probably prevent you from getting your value out of the billemail element (input?).

More importantly, you're mis-matching quotes, so your JS at large is invalid:

alert ("Billing email is '+data+'!");   // <-- Need double-quotes
                        ^^^    ^^^

Try fixing that and see if you get a better result.
