AJAX and wordpress

Hi guys the current ajax call shows the post content, how can i make it display post title and custom fields? any hint? im going mad.

case 'load_more_content':
					$postid = $base->getPostVar('postid', 0, 'i');
					if($postid > 0){
						$raw_content = get_post_field('post_content', $postid);
						if(!is_wp_error($raw_content)){
							$content = apply_filters('the_content', $raw_content); //filter apply for qTranslate and other
							self::ajaxResponseData($content);
						}

					}
					$error = __('Post Not Found', EG_TEXTDOMAIN);
				break;
