.click() jquery function not working

I have wrote this code in php:
public function getinfo($username){
$this->autoRender = false;
if($this->request->is('ajax')){
if(!ereg('^[A-Za-z0-9_.]+$',$username)){
echo 'username';
}
else{
$user =
$this->User->find('all',array('conditions'=>array('User.username'=>$username)));
if(empty($user)){
echo 'Fail';
}
else{
$this->loadModel('Question');
$question =
$this->Question->find('all',array('conditions'=>array('Question.id'=>$user[0]['User']['questionid'])));
echo 'Sec Question : ' .
$question[0]['Question']['title'] . '<br />';
echo 'Answer: <input type="text" id="userAnswer"
class="loginField" name="data[answer]" /> ';
echo '<input type="submit" id="sendAnswer"
class="button" value="send" /> <br />';
echo '<span id="recoverErr"></span>';
$this->Session->write('recoverPass',$user[0]);
}
}
}
else{
$this->redirect(array('controller'=>'message','action'=>'forbidden'));
}
}
And I have wrote this in my jquery file:
$('#send').click(function(){
var recover = $('#recoverUsername').val();
$('#recErr').css('color', 'red');
if(recover == ''){
$('#recoverUsername').focus();
$('#recErr').html('Enter username');
return false;
}
$.ajax({
url: $('#base').html() + '/users/getinfo/'+recover,
type: 'POST',
success: function(data){
if(data.match('username')){
$('#recErr').html('Enter correct username.');
}
else if(data.match('Fail')){
$('#recErr').html("This username doesn't exist");
}
else{
$('#recErr').html('');
$('#recoverWindow').html(data);
$('#recoverWindow').dialog('open');
});
}
}
});
});
$('#sendAnswer').click(function(){
var answer = $('#userAnswer').val();
$.ajax({
url: $('#base').html() + '/users/getanswer/'+answer,
type: 'POST',
success: function(data){
if(data.match('answer')){
$('#recoverErr').html('Enter answer');
}
else if(data.match('Fail')){
$('#recoverErr').html('answer is false.');
}
else if(data.match('Bad')){
$('#recoverErr').html('fail too send mail.');
}
else{
$('#recoverWindow').html('');
$('#recoverWindow').html('Email was sent,
check your spam if it is not in your
inbox.');
}
}
});
but when I click and the server found the User's info and put it in

to the action. please Help me, i don't have time
