Like this..

$(".dropdown-menu li a").click(function(){
  var selText = $(this).text();
  console.log( selText);
  $(this).parents('.dropdown').find('.dropdown-toggle').val(selText);
});

I'm not sure I 100% understand what you are trying to do. For clarity, you want the li to change to the button's id and value? If so try this:

    $(".dropdown-menu li a").click(function(){
    document.getElementById("admin_cal_list").innerHTML = $(".dropdown-toggle").attr("id") + " " + $(".dropdown-toggle").attr("value");
});
