Question

My demo, is really clear, when I clone my element
I clone and delete the divs however, the :last element (li) should’t been removed.
what I’m missing?

is something to do with this!:

$(document).on("click", 'li.delete',function () {
            $(this).closest(".outerDiv").remove();
    if ($(this).is(".outerDiv:last")){
            return false;
    }

try this code

var cloneCount = 0;
$("#add-address").click(function() {

    $("#to-add-address").clone()
        .attr("id", "to-add-address_Clone" + cloneCount)
        .insertAfter("#to-add-address").addClass('cloned');  //add a new class cloned to the cloned outerDivs
    $("#clone", "#to-add-address_Clone" + cloneCount)
        .attr("id", "clone_Clone" + cloneCount);
    cloneCount++;
});

$(document).on("click", '.options li a',function () {
            $(this).closest(".options").find('li a').removeClass('selected');
            $(this).addClass('selected');

        });
$(document).on("click", 'li.delete',function () {
            $(this).closest(".outerDiv").filter('.cloned').remove(); // and delete only the cloned ones
    if ($(this).is(".outerDiv:last")){
            return false;
    }   
});
