				if(arguments.length < 2) {

				// If qTip is rendered and title was originally used as content, update it
				if(api && api.options.content.attr === title && api.cache.attr) {
					api.set('content.text', val);
				}

				// Use the regular attr method to set, then cache the result
				return this.attr(oldtitle, val);
			}
