Thanks to tmg for his code, heres the correct html code for those who are looking for the ready code.

$(document).ready(function() {
       $('#myCarousel').on('slide.bs.carousel', function (ev) {
       var idx = $(ev.relatedTarget).index() + 1;
/*       console.log(idx);*/
       idx = parseInt(idx);
        switch (idx) {
          case1:
            $('#sometext').text("one");
            break;
          case2:
            $('#sometext').text("two");
            break;
          case3:
            $('#sometext').text("three");
          default:
            //the id is none of the above
            $('#sometext').text("default");
        }
