React cart empty function

Question

I am new with react, I have a cart and I want it empty when a user place an order. I have a function that empties the cart "resetCartList" that I did in the context provider and it is already in Cart.jsx, but I do not know where to put it due to I have an onclick that already place the order. Below is the code: This is the Cart.jsx:

import { useState } from "react";
import { Button, Col, Container, Form, Table } from "react-bootstrap";
import { Link } from "react-router-dom";
import { useCartContext } from "../../Context/CartContext";
import { getFirestore } from "../../firebase";
import firebase from "firebase/app";
import "firebase/firestore";

const CartComponent = ({ header = false }) => {
  const {
    list,
    totalPrice,
    deleteProd,
    orderId,
    setOrderId,
    date,
    setDate,
    resetCartList,
  } = useCartContext();
  const [name, setName] = useState("");
  const [email, setEmail] = useState("");
  const [phone, setPhone] = useState("");

  let datePurchase = new Date();
  setDate(datePurchase.toLocaleString());
  const placeOrder = () => {
    let newOrder = {
      Buyer: { name: name, email: email, phone: phone },
      items: [...list],
      Date: firebase.firestore.FieldValue.serverTimestamp(),
      total: totalPrice(),
    };
    console.log("newOreder", newOrder);
    const fsDB = getFirestore();
    const orederCollection = fsDB.collection("orders");
    orederCollection.add(newOrder).then((value) => {
      setOrderId(value.id);
    });
  };

  return (
    <>
      {!header && <h1 className="py-4 text-center text-muted">Cart</h1>}
      {list.length > 0 ? (
        <div>
          <Container>
            <Table striped hover className="text-muted">

                  <th>Price</th>
                  {!header && <th>&nbsp;</th>}
                </tr>
              </thead>
              <tbody>
                {list.map((varietal) => (
                  <tr key={varietal.id}>

                      <img

                        style={{ width: "82px" }}

You can call multiple functions in handlers with creating new function like this:

<Button
  variant="info"
  className="mx-auto my-4 d-block"
  size="lg"
  onClick={() => {
    placeOrder();
    resetCartList();
  }}
>
  Place order
</Button>
