Hide text boxed in multiple answer questions

Hi!
I have a question that has multiple answers that have the option to allow text entry.
i'd like to hide the all text boxes until the customer selects the option.
Qualtrics.SurveyEngine.addOnReady(function () {

  var text_box = this.getChoiceContainer().querySelector(".TextEntryBox");
  text_box.hide();

  this.questionclick = function () {
    var text_choice = text_box.ancestors()[1].children[1].className.includes("checked");
    if (text_choice) {
      text_box.show();
    } else {
      text_box.hide();
    }
  };
});

I have this one but it just works to hide one text box out of the 4.
