Google Chrome is not caching web page

My web app's pages don't seem to be cached (bfcache) in google chrome. It works well with firefox and even with qupzilla.

I wanted the pages to be left as is when the user opens a link and back but this doesn't seem to work with chrome. When I press the back button it reloads the page, $(document).ready() is called.

Google Chrome: Version 46.0.2490.71 (64-bit)
