element.addEventListener not adding listener - html

Question

So I have an array of strings that will turn into buttons,
//At start
function acceptSuggestion() {
console.log(`clicked`)
console.log(this.textContent);
}
//Else where
suggestions.couldBe.innerHTML = ``;
list.suggestions.forEach(function (item) {
let button = document.createElement(`button`);
button.textContent = item;
button.addEventListener(`click`, acceptSuggestion);//before append
button.style = `text-align:center; width:50%`;
suggestions.couldBe.appendChild(button);
button.addEventListener(`click`, acceptSuggestion);//after append
suggestions.couldBe.innerHTML+=`<br>`;
});
It creates the buttons fine
But clicking them does nothing.
Why is this? I know I have the event right cuz of this: https://www.w3schools.com/js/js_htmldom_eventlistener.asp
If it matters, I am using electron.js to create an webpage like application, and not a browser.

Answer 1

The reason this is happening is because of this line:
suggestions.couldBe.innerHTML+="<br>";
What is happening is your Browser element is generating all new fresh HTML each loop because of the += on the innerHTML.
Basically in pseudo code:
var temp = suggestions.couldBe.innerHTML + "<br>;
suggestions.couldBe.innerHTML = temp;
This causes your element that was added via the suggestions.couldBe.appendChild(button); to be converted to html, then re-parsed and all new elements created from HTML each iteration of the loop. Because your Button event handler was created in JS; it is lost when it recreated the button from the HTML version.
You want to do this either all via JS; not mixing it. So my suggestion would be to change this line:
suggestions.couldBe.innerHTML+="<br>";
to
suggestions.couldBe.appendChild(document.createElement('br'));
