title: How to change "Devise: password reset instruction email's subject"
body: <p>I'm just unable to change "password reset instruction" email's subject. I have changed notifer.rb in Mailer to overwrite Devise default email subject. But it's not working.</p>
  
  <p>Here in my application there is default Email subject inside Devise .yml file. But I want to make it dynamic to change it by pulling data from DB.</p>
