from my response on your other question:

I don't see button defined, but probably more importantly, you don't want to be handling buttons inside your populateIdWithHTML function, which should just look like this:

  populateIdWithHTML: function(id, text) {
    var element = document.getElementById(id);
    element.innerText = text;
  }

Then, you want to add the event handlers inside the displayChoices function, like so:

  displayChoices: function() {
    var choices = quiz.getCutrrentQuestion().choices;

    for (var i = 0; i < choices.length; i++) {
      this.populateIdWithHTML("choice" + i, choices[i]);
      var button = document.getElementById('guess' + i);
      button.addEventListener("click", function() {
        // put whatever you want it to do on button press here 
      });
    }
  }
