RubyMine 7 does not update project folder to update new file

Question

I installed RubyMine 7 on ubuntu 14.04. When you create a file using rails generate, rubyine do not update the update tree folder to update a new file in the project folder. So I can’t open the file or do something. I always click the TT sync folder manually. But when I use rails destroy to delete some file, the ruby ​​update tree updates when I click on it.
