require(['dojo/on', 'dojo/domReady!'], function (on) {

  on(dojo.byId('my-span'), 'click', function (e) {
    alert('I throw an alert');
    alert('And do it again');
    alert('And again');
  });

  on(dojo.byId('my-other-span'), 'click', function (e) {
    alert('I throw an alert');
    alert('And do it again');
    alert('And again');
  });

});

<script type="application/javascript" src="//ajax.googleapis.com/ajax/libs/dojo/1.10.4/dojo/dojo.js"></script>
<span id="my-span">Click me!</span>
<span id="my-other-span">Click me too!</span>
