use click event on the response message sent using jquery/ajax

use click event on the response message sent using jquery/ajax

I get a response message from the php file when i ajax to communicate to the db using $.get

i have an id assigned to my return message and would like to trigger events to that as well but it does not work.

below is the code that calls my php file and passes the callback function (show_data)
[code]

function start(){
$("#tt").click(send_data);
}

$("#rr").click(send_data);

function send_data(){
$.get('ret.php?',show_data)
}

function show_data(res){
$('#result').html(res);
}

$(document).ready(start);
[/code]
//id rr is my return messages id on which i wish to fire an event.
my php code is below
[code]

$ret = "<span id=rr>CLICK HERE</span>";
echo $ret;
[/code]
