title: Creating a new user and also add new data to the firebase database at every SignUp
body: <p>I am new to Android programming. I am working on an app. When I signup in my app this shows the previously added data and does not ask me to add new user data to the database.<br>
  Even if I again login with a registered user then it again shows the previously added data.<br>
  I want that when I create a new user then a new node should create and then its child with data.</p>
