I am trying to change the button that is clicked to 'COPIED!'. However, only the 1st button works. The other buttons don't change to 'COPIED!' after clicking.

The issue lies in the last part of the code. However, I can't seem to get around it.

Any help is appreciated.

Code:

<pre><div id="test"></div>

const alphabet1 = ["Λ", "B", "C", "D", "E"];

let txt2 = "ΛΛ";
let final = "";

// loop to add all the possible version of writing the word consisting ΛΛ ('_ΛΛ_ _')
for (let i = 0; i < alphabet1.length; i++) {
  for (let j = 0; j < alphabet1.length; j++) {
    for (let k = 0; k < alphabet1.length; k++) {
      final += "<button onclick=\"copy(this)\"><span id=\"copied\">" + alphabet1[i] + txt2 + alphabet1[j] + alphabet1[k] + "</span></button>";
    }
  }
}
document.getElementById("test").innerHTML = final;

// copies text to clipboard
function copy(that) {
  var inp = document.createElement("input");
  document.body.appendChild(inp)
  inp.value = that.textContent
  inp.select();
  document.execCommand("copy", false);
  inp.remove();
}

// changes the text to COPIED! on click for 1000ms
document.getElementById("copied").addEventListener("click", function(clicked) {
  return function() {
    if (!clicked) {
      var last = this.innerHTML;
      this.innerHTML = "COPIED!";
      clicked = true;
      setTimeout(function() {
        this.innerHTML = last;
        clicked = false;
      }.bind(this), 1000);
    }
  };
}(false), this);

What I have tried:

document.getElementById("copied").addEventListener("click", function (clicked) {
            return function () {
                if (!clicked) {
                    var last = this.innerHTML;
                    this.innerHTML = "COPIED!";
                    clicked = true;
                    setTimeout(function () {
                        this.innerHTML = last;
                        clicked = false;
                    }.bind(this), 1000);
                }
            };
        }(false), this);
