popstate working for internet explorer but not for chrome

i want to call a function when browser back button is clicked. bellows code is working for internet explorer but not for chrome. i dont know whats wrong with this.

jQuery(document).ready(function($) {

  if (window.history && window.history.pushState) {

   window.history.pushState('forward', null, './#forward');

    $(window).on('popstate', function() {
      alert('dcu');
      window.location.href = "competition";
    });
