Here is my server side expose code..

if(!$username){
$user = get_loggedin_user();
} else {
$user = get_user_by_username('surajkumar9890');
}
if (!$user) {
throw new InvalidParameterException('registration:usernamenotvalid');
}
$owner = get_entity($user->guid);
$profile_fields = elgg_get_config('profile_fields');
foreach ($profile_fields as $shortname => $valuetype) {
$value = $profile[$shortname];
$value = html_entity_decode($value, ENT_COMPAT, 'UTF-8');

    if ($valuetype != 'longtext' && elgg_strlen($value) > 250) {
        $error = elgg_echo('profile:field_too_long', array(elgg_echo("profile:{$shortname}")));
        return $error;
    }

    if ($valuetype == 'tags'){
        $value = string_to_tag_array($value);
    }
    $input[$shortname] = $value;
}

$name = strip_tags($profile['name']);
if ($name) {
    if (elgg_strlen($name) > 50) {
        return elgg_echo('user:name:fail');
    } elseif ($owner->name != $name) {
        $owner->name = $name;
        return $owner->save();
        if (!$owner->save()) {
            return elgg_echo('user:name:fail');
        }
    }
}

if (sizeof($input) > 0) {
    foreach ($input as $shortname => $value) {
        $options = array(
            'guid' => $owner->guid,
            'metadata_name' => $shortname
        );
        elgg_delete_metadata($options);

        if (isset($accesslevel[$shortname])) {
            $access_id = (int) $accesslevel[$shortname];
        } else {
            // this should never be executed since the access level should always be set
            $access_id = ACCESS_DEFAULT;
        }

        if (is_array($value)) {
            $i = 0;
            foreach ($value as $interval) {
                $i++;
                $multiple = ($i > 1) ? TRUE : FALSE;
                create_metadata($owner->guid, $shortname, $interval, 'text', $owner->guid, $access_id, $multiple);
            }

        }else{
            create_metadata($owner->guid, $shortname, $value, 'text', $owner->guid, $access_id);
        }
    }
}

return "Success";

}

if($_SERVER['REQUEST_METHOD'] == "POST"){
expose_function('user.save_profile',

            });
        }
    }
});

have you tried escaping the the @ character? This project is getting pretty old now and elgg could really do with a fresh restFul interface.
