Change Background color of Active list item in bootstrap

Don't know why bootstrap isn't doing it, but here's some jQuery on a fiddle for you. The alert is displaying the href that is active.

Is that what you're after?

Edited the old fiddle, here's the new one http://jsfiddle.net/dh7t3cbp/1/

$('.list-group').on('click', '> a', function(e) {
  var $this = $(this);
  $('.list-group').find('.active').removeClass('active');
  $this.addClass('active');

  alert($this.attr('href') + ' is active');
});

$('.list-group .collapse').on('click', '> a', function(e) {
  var $this = $(this),
    $parent = $this.parent('.collapse');
  $parent.find('.active').removeClass('active');
  $this.addClass('active');

  alert($this.attr('href') + ' is active');
});

.list-group panel.active, .list-group panel.active a.active {
  background-color: #030;
  border-color: #aed248;
}

What i does it assign and id to every link in list that is also the page name, and made a js function that is called on body load of the page. the function get the current file name from url and determines which page is this, then by js i made that link class active. this solve my problem. however i share this solution for others to improvement.

function get_current_page() {
  var pathArray = window.location.pathname.split("/");
  var current_page = pathArray[pathArray.length - 1];
  current_page_array = current_page.split(".");
  current_page = current_page_array[0];

  if (
    current_page == "students" ||
    current_page == "my-profile" ||
    current_page == "faqs" ||
    current_page == "forecast-career"
  ) {
    document.getElementById("joinuslist").className += " active";
    document.getElementById("joinus").className += " in";

    if (current_page == "students") {
      document.getElementById("students").className += " active";
    } else if (current_page == "faqs") {
      document.getElementById("faqs").className += " active";
    } else if (current_page == "forecast-career") {
      document.getElementById("forecast-career").className += " active";
    } else if (current_page == "my-profile") {
      document.getElementById("my-profile").className += " active";
    } else {
    }
  } else if (
    current_page == "values" ||
    current_page == "ambassadors" ||
    current_page == "documentary"
  ) {
    if (current_page == "values") {
      document.getElementById("values").className += " active";
    } else if (current_page == "ambassadors") {
      document.getElementById("ambassadors").className += " active";
    } else if (current_page == "documentary") {
      document.getElementById("documentary").className += " active";
    } else {
    }
  }
}
