JavaScript Create a Reusable Fetch Function

Doggo Select. The images come up upon selecting the breed type but the image doesn't change when i click on it.

Ive checked the code up and down in comparison to the one in the video. I figured it was something to do with the event listener but it isn't any different then it is in the videos. Also i was wondering if it had to do with the fact that in the api url it says "breeds" but in the fetchBreedImage it doesn't but when i change one or the other the link is broken

const select = document.getElementById('breeds');
const card = document.querySelector('.card'); 
const form = document.querySelector('form');

// ------------------------------------------
//  FETCH FUNCTIONS
// ------------------------------------------

function fetchData(url){
    return fetch(url)
        .then(res => res.json())
};



fetchData('https://dog.ceo/api/breeds/list')
    .then (data => generateOptions(data.message))




fetchData('https://dog.ceo/api/breeds/image/random')
  .then ( data => generateImage(data.message))



// ------------------------------------------
//  HELPER FUNCTIONS
// ------------------------------------------




function generateOptions(data){
    const options = data.map( item => `
        <option value='${item}'>${item}</option>

    `).join('');
select.innerHTML = options; 
}



function generateImage(data){
    const html = `
        <img src='${data}' alt>
        <p>Click to view images of ${select.value}s</p>
    `;
    card.innerHTML = html;
}


function fetchBreedImage(){
    const breed = select.value;
    const img = card.querySelector('img');
    const p = card.querySelector('p');

    fetchData(`https://dog.ceo/api/breed/${breed}/images/random`)
        .then(data => {
            img.src = data.message;
            img.alt = breed;
            p.textContent = `Click to view more ${breed}s`
        })

}


// ------------------------------------------
//  EVENT LISTENERS
// ------------------------------------------
select.addEventListener('change', fetchBreedImage);
card.addEventListener('change', fetchBreedImage);


// ------------------------------------------
//  POST DATA
// ------------------------------------------

The message states "Click to view more" so you will want to handle the click event.

You have:

card.addEventListener('change', fetchBreedImage);

It should be:

card.addEventListener('click', fetchBreedImage);
