Heroku displays old index.html even after I have deleted it and git commit

After I have re-deployed my app to Heroku, it displays the old public/index.html. What am I missing?

I have done the following steps:

1. $ git rm public/index.html
2. fix the routes.r开发者_高级运维b to add root :to => "homes#index"
3. $ git add .
4. $ git commit -m "changes"
5. $ git clean -f
6. $ git push heroku branch-name:master
7. $ heroku rake:db:migrate
8. $ heroku db:push
9. $ heroku open

There is no need to clean. Just do a simple rm (not git rm) and then git add -A before you commit.

Hope this helps
