Firebase web app - can't get user.uid when creating new account

I am working on a small web app and I have hit a roadblock that I can't seem to overcome. I am able to register a new account, but I would like to save additional data to a database right after signing up.

This is what I have that I am confident that works fine. 

$("#user-sign-up-button").click(function(){


  var firstName = $("#new-user-first-name").val();
  var secondName = $("#new-user-surname").val();
  var charity = $("#new-user-charity-account").val();
  var userEmail = $("#new-user-email").val();
  var userPassword = $("#new-user-password").val();
  var secondPassword = $("#new-user-repeated").val();

  firebase.auth().createUserWithEmailAndPassword(userEmail, userPassword)
  
  .catch(function(error) {
    // Handle Errors here.
    var errorCode = error.code;
    var errorMessage = error.message;
    // ...
  });


});

Now in regards to saving the additional variables to the database I have tried both of the below within .then part of createuserWithEmailAndPassword.

.then(
    function(user){
      var root = firebase.database().ref();
      var uid = user.uid;
      alert(uid);
      var postData = {  firstName: first_name,
        secondName: second_name,
        email: user_email,
        isCharity: charity };
        root.child("users").child(uid).set(postData);
    }

    function writeUserData(first_name, second_name, charity, user_email) {
      firebase.database().ref('users/' + user.uid).set({
        firstName: first_name,
        secondName: second_name,
        email: user_email,
        isCharity: charity
    });
  )

Both of the above solutions work within onAuthStateChanged but I want to capture the data at sign up, not every time someone signs in.

Any assistance would be great.

You must use .onAuthStateChanged to get at firebase.auth().currentUser. It's asynchronous and will be empty/null until it resolves. Also, don't forget that new email based accounts will not be .emailValidated:true until they have clicked a verification email link. ...something to consider.
