Just wait until Google made some updates and see the result..

Wait and see becasue google may get your new page cache. try to submit to digg or some place that have bot.

When did you last optimize your website? Isn't it just
1 day or 2 days ago? I was having the same question in
my mind when the site I was working with has not yet
been index again though I optimize it.. And then after
a week it was index.. So all I can say was patience is
really needed.. after all you have done right to your site

After upadating a site, you will have to SEO work for this site.then google will re-index your updating site. keep patience.

google can only show the old site that they've crawl, before you make some changes

You can do either of the following to help you get index:

1. Search Engine Submissions
2. Build Links - back links helps your site get index.
3. Creating a sitemap - it helps your sub-pages get listed.
