Missing span style tag from ajax jQuery to PHP

Hi, im trying to implements CKeditor on Codeigniter framework. I can load, instance and config as well but when i submit textarea's content with jQuery ajax in JSON string format, span's style tag disappear on PHP server side.

Here is my javascript function

function debug(){
    var vcadena = JSON.stringify($("#ncuerpo").val(), null, 2);
    $.ajax({
        type: "POST",
        url: "/administrar/noticias/serverdebug",
        data: ({cadena:vcadena})
    });
}

Codeigniter uses

$this->input->post('postVariable')

instead native PHP's method

$_POST['postVariable']

If i print $this->input->post('postVariable') before json_decode i can see the string:

"<p>\n\t<span>Im a colored string</span></p>\n"

as u can see, style tag isnt there

And what about this one:

$.ajax({
        type: "POST",
        url: "/administrar/noticias/serverdebug",
        data: ({cadena:'"<p><span style=\\"color:#CCCCCC\\">Im a colored string</span></p>"'})
    });

Does it work ok?

No it doesn't, but i found the problem.

The Input class has the ability to filter input automatically to prevent cross-site scripting attacks. If you want the filter to run automatically every time it encounters POST or COOKIE data you can enable it by opening your application/config/config.php file and setting this:
$config['global_xss_filtering'] = TRUE;

Just setting to FALSE solve the problem.
Thanks for fast replies
