You need the response to be

{"records":[{"email":"test@test.com","name":"test"}
..

Try

#!/usr/bin/perl -w
use strict;
use warnings;
use CGI;
use DBI;
use JSON;
my %output=();
my $dbh = DBI->connect("dbi:mysql:database=test","usern","userp")  
  or die "Connecting from Perl to MySQL database failed: $DBI::errstr"
+;
my $sth = $dbh->prepare('SELECT name, email FROM user_tb');
$sth->execute;
while ( my $row = $sth->fetchrow_hashref ){ 
    push @{$output{'records'}}, $row;
}
my $cgi = CGI->new;
print $cgi->header( 'application/json' );
print to_json( \%output );
[download]

or leave cgi and change the html. Remove .records and use

$scope.names = response.data;

or just change last line of cgi to

print to_json( { 'records' => \@output } );
