Hi,
If you would like to see how google 'sees' your website, please sign into Google Webmaster Tools https://www.google.com/webmasters/tools/home?hl=en , verify your website, and one of the options lets you see your site through the all seeing eyes of the Google spider.
Normally anything that is javascript is not read, though maybe because the tabs are reloaded and don't require a push of the tab to load anything, maybe they are available. and not being triggered by anything, perhaps Google spider is smart enough to see it after all. Your best bet is to spend 5 min setting up GW Tools and test it, also that place provides lots of useful optimization info and extends Analytics, so definitely worth the trouble of signing up.
Thanks,
Nick
