Removing item from the list

Hi Team

I have cart item and want to remove using button, but when debug i get this error and " Uncaught ReferenceError: removeItemFromCart is not defined".Below is my add-to-cart.js logic and have used delegates but still unlucky.

$(document).ready(function() {
  $(".add-to-cart-btn").click(function(e) {
    e.preventDefault();

      var productId = $(this).data("id");
      console.log("Product ID:", productId);
      var productName = $(this).data("product-name");
      var productImage = $(this).data("product-image");

      var quantity = parseInt($("#quantity-input").val());
      //store the product ID in the session.
      var productImage = "img/" + productId + ".jpg";

      var productPrice = parseFloat($("#product-price-" + productId).text().replace("R", ""));
      var totalPrice = productPrice * quantity;

      //store the product details in the session.
      var cartItems = JSON.parse(sessionStorage.getItem("cartItems")) || [];
      cartItems.push({
          productId: productId,
          quantity: quantity,
          productImage: productImage,
          productName: productName
      });

      sessionStorage.setItem("cartItems", JSON.stringify(cartItems));
    $.ajax({
      type: "POST",
      url: "add-to-cart.php",
      data: { productId: productId },
      success: function(response) {
        alert(response);
        updateCartBadge(); // Update the cart badge with the new count
        getCartItem(); // Refresh the cart items after adding
      },
      error: function(xhr, status, error) {
        alert("An error occurred while adding the item to the cart.");
        console.log(xhr.responseText);
      }
    });
  });

    // Function to update cart badge.
    function updateCartBadge(userId) {
        $.ajax({
            type: "GET",
            url: "getCartItemCount.php",
            data: { userId: userId},
    success: function (response) {
        console.log('Cart Item Count:', response);
        $("#cart-badge").text(response); // Update the cart badge count
    },
    error: function (xhr, status, error) {
        alert("An error occurred while retrieving the cart item count.");
        console.log(xhr.responseText);

    cartContainer.empty();

    // Loop through the cart items and add them to the HTML
    cartItems.forEach(function (item) {
        var totalPrice = item.totalPrice || 0; // Ensure totalPrice is a valid number or set it to 0
        var cartItemHtml = `
            
                ${item.product_name}
                
                R${totalPrice.toFixed(2)}
                ${item.quantity}
                Remove

            
        `;

        cartContainer.append(cartItemHtml);
