Using custom backgrounds for buttons created through JavaScript

Question

Trying to have a button created in JavaScript to use the background image of the specific API image I seen many suggestions to use .style.backgroundImage = 'Url("yourimagelink")';. But can't seem to figure it out.

Updated to include my function.

//  The "addListItem" function creates li and button for item names also creates event on click

function addListItem(item) {
    let groupList = document.querySelector('.list-group');

    let listItem = document.createElement('li');
    listItem.classList.add('list-group-item');

    let button = document.createElement('button');
    button.classList.add('btn-image');
    button.innerText = item.name;
    button.style.backgroundImage = 'Url("item.imageUrl")';

    listItem.appendChild(button);

    groupList.appendChild(listItem);

    button.addEventListener('click', function () {
        showDetails(item);
    });
};

No image appears and no errors too.

You should add the button to the DOM, using appendChild for example, createElement only creates the button instance, it is not added to the DOM.

Working example below:

item = { name: 'test', imageUrl: 'https://images.unsplash.com/profile-1446404465118-3a53b909cc82?ixlib=rb-0.3.5&q=80&fm=jpg&crop=faces&cs=tinysrgb&fit=crop&h=32&w=32&s=a2f8c40e39b8dfee1534eb32acfa6bc7' };

let button = document.createElement('button'); // It only create the button instance, but don't add it to the DOM
document.body.appendChild(button); // You should add the button to the DOM
button.classList.add('btn-image');
button.innerText = item.name;
button.style.backgroundImage = `url(${item.imageUrl})`;
