DropDown Menu not Changing

Here is my JavaScript code:

$(function() {
$(function () { 
$(".ConnectionOption").each(function () { 
    var waardown = $(this).attr("id"); 
    var option = $('#ConnectionOption'); 
    option.css("display", "block"); 
    $(this).autoSelect(); 
}); 
console.log(waardown); 
}); 

When I click on the option a dropdown menu will not change. Why?
