Remove Item from shopping cart does not work

REMOVE button does not work. Even in console when i click the button nothing appears in the console. Can anyone spot the problem?

I feel like something is wrong with the classes, not sure though.

This JS for shopping cart. Is the whole js code its just the function that included the remove button functionality.

if(document.readyState == "loading") {
    document.addEventListener("DOMContentLoaded", ready)
} else {
    ready()
}

function ready() {
var removeCartItemButtons = document.getElementsByClassName("btn-danger")
console.log(removeCartItemButtons)
for (var i = 0; i < removeCartItemButtons.length; i++) {
    var button = removeCartItemButtons[i]
    button.addEventListener("click", removeCartItem) 
    console.log("click")
    }

var quantityInputs = document.getElementsByClassName("quantity__item")
for (var i = 0; i < quantityInputs.length; i++) {
    var input = quantityInputs[i]
    input.addEventListener("change", quantityChanged)
    }

    var addToCartButtons = document.getElementsByClassName("shop-item-button")
    for (var i = 0; i < addToCartButtons.length; i++) {
        var button = addToCartButtons[i]
        button.addEventListener("click", addToCartClicked)
    }

    document.getElementsByClassName('btn-purchase')[0].addEventListener('click', purchaseClicked)
}
