Adding user data into firestore after Firebase Auth

Question

I'm trying to add User data into Cloud Firestore after using Firestore Auth when a new user is created.

$("#signup_btn").click(function () {
    var firstname = document.getElementById("firstname").value;
    var lastname = document.getElementById("lastname").value;
    var email = document.getElementById("email_signup").value;
    var password = document.getElementById("password_signup").value;

    firebase.auth().createUserWithEmailAndPassword(email, password).then(cred=>{
        this.createNewUserData(firstname,lastname,email);
    }).catch(error =>{
        var user = firebase.auth().currentUser;

        user.delete();
        var errorMessage = error.message;

        window.alert("Error: "+ errorMessage);
    });
});


function createNewUserData(firstname, lastname, email){
    db.collection("users").add({
        firstname: firstname,
        lastname: lastname,
        email: email
    })
        .then(function (docRef) {
            console.log("Document written with ID: ", docRef.id);
        })
        .catch(function (error) {
            console.error("Error adding document: ", error);
        });
}

The above code I've implemented is able to add user data into the firebase Auth however it doesn't add any data into the firestore database. Is there a better way to implement this function?

You cannot call another function using this.createNewUserData. Thus, you need to call createNewUserData(firstname,lastname,email); from the then block of createUserWithEmailAndPassword.

Currently,the reason that the it does not add any user data into the firestore database is that the function createNewUserData is not called. So, once that function is called you will get at least a call to firestore to add that user.
