Cannot receive data with POE tcp connection

Hi,

I'm build simple application using POE for receiving data from gps 
tracker with tcp connection. But i can't receive the data. And then I 
try write the code into python, and I get the data from tracker. This is 
my simple code with Perl :

#!/usr/bin/perl -w

use warnings;
use strict;
use POE qw(Component::Server::TCP);


POE::Component::Server::TCP->new(
         Port => 37773,
         ClientConnected => sub {
          print "I got a connection from $_[HEAP]{remote_ip}\n";
         },
     ClientInput => sub {
         print "doing something..\n";
             my ($sender, $heap, $input) = @_[SESSION, HEAP, ARG0];
             print "RECIEVED: " . $input . "\n";
         },
);

POE::Kernel->run;
exit;

And in simple python code :

import socket
server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind(("",37773))
server_socket.listen(5)

print "TCPServer Waiting for client on port 37773"

while 1:
         client_socket, address = server_socket.accept()
         print "I got a connection from ", address
         while 1:

                 data = client_socket.recv(512)
                 print "RECIEVED:" , data

In the POE code when I run it, just accept that there is a connection 
from the tracker, but the data does not exist.

With python :

Can you help me about this guys, how I can receive data using POE? Sorry 
if my english bad.

Thanks.
