extra input added by jquery doesn't work - php

Question

Hi I'm trying to get a dinamically input added with Jquery, but when I try to get the code it's not working
The code in codeigniter catch all POST but less the one added by jquery
here is the code:
<script type="text/javascript">
$(document).ready(function(){
var value = parseFloat($("#subtotal").val());
$('.subtotal').html(value);
$('#subtotal').val(value);
$('input[name="phprop"]').change(function(event){
if($('input[name="phprop"]:checked').val() == 'Yes'){
$('#sections').show();
}else if($('input[name="phprop"]:checked').val() == 'No'){ $('#sections').hide();}
});
$('input[name="xsst"]').change(function(event){
if($('input[name="xsst"]:checked').val() == 'Yes'){
$('#xtraphotos').show();
$('<input type="text" name="extraid'+i+'" id="extraid'+ i +'" style="width:80px;margin-left:4px;"/>').appendTo('#xtrabox');
var num = value + 9.95;
value = parseFloat(num.toFixed(2));
$('.subtotal').html(value);
$('#subtotal').val(value);
$('#extrass').val(i); i++;
}else if($('input[name="xsst"]:checked').val() == 'No'){
$('#xtraphotos').hide();
$('#xtraphotos input[type="text"]').remove();
var num = value - 9.95 * (i - 1);
value = parseFloat(num.toFixed(2));
$('.subtotal').html(value);
$('#subtotal').val(value);
$('#extrass').val(0);
i = 1;
}
});
var scntDiv = $('#xtrabox');
var i = 1;
$('#addScnt').live('click', function() {
$('<input type="text" name="extraid'+i+'" id="extraid'+ i +'" style="width:80px;margin-left:4px;"/>').appendTo(scntDiv);
num = value + 9.95;
value = parseFloat(num.toFixed(2));
$('.subtotal').html(value);
$('#subtotal').val(value);
$('#extrass').val(i);
i++;
return false;
});
});
</script>
Here is the HTML
<div style="margin-left: 50px;">
<label><b>Do you need more photos for your web?</b> </label>Yes<input type="radio" name="xsst" id="xsst" value="Yes"/>No<input type="radio" name="xsst" id="xsst" value="No"/> (Each aditional photo has a cost of <b>$9.95</b>)
<div id="xtraphotos" style="display:none;">Add another picture box<div id="xtrabox"></div></div></div>
Here is the Codeigniter code:
if($_POST['extrass'] !=0){
for($i=1;$i<=$_POST['extrass'];$i++){
$names = "extraid".$i;
$extras .= $_POST[$names];
if($i!=$_POST['extrass']){
$extras .= "-";
}
}
Here is the complete HTML (Just the form Section):
<?php echo form_open_multipart(base_url() . 'purchase/confirmation')?>

Your HTML have a tag form?
When.you not put forms elements inside a form, onload, some brownser add a form to correct code syntax... But when you add nes elements using DOM, maybe this elements not include inside this form...
