How to call a function from checkbox onclick or onchange

I have a form in which i want to disable or hide two input fields by selecting a checkbox. I can easily do it when on document.ready, but since i am appending those fields the function does not take effect. How do i call the function with onClick?

Here's my working code

$(function() {
  $(checkbox).click(function() {
    if ($('#checkbox').is(':checked')) {
      $('#appTimes').find('input').attr('disabled', true);
    } else {
      $('#appTimes').find('input').removeAttr('disabled');
    }
  });
});

<script src="http://ift.tt/1oMJErh"></script>
<div class="appTimes" id="appTimes">
  <input name="stopTime1" type="text" id="stopTime1" />
  <input name="stopTime12" type="text" id="stopTime12" />
</div>
<input name="checkbox" type="checkbox" id="checkbox" />

And this is what i am trying to do:

function boxDisable(e) {
  $(this).click(function() {
    if ($(this).is(':checked')) {
      $(e).find('input').attr('disabled', true);
    } else {
      $(e).find('input').removeAttr('disabled');
    }
  });
}

<div class="appTimes" id="appTimes">
  <input name="stopTime1" type="text" id="stopTime1" />
  <input name="stopTime12" type="text" id="stopTime12" />
</div>
<input name="checkbox" onclick="boxdisable(appTimes);" type="checkbox" id="checkbox" />
