I don't really understand your question and think it needs some clarifying - but as far as I could understand (I ran into this problem and found your question when Googleing it...)

When I first load the page I run the following JavaScript so that all of my drop-down select boxes are styled and using select2:

$('select').select2();

But as your title states, my code below works by updating the drop-down to a new set of data -where my /store/ajax_get_zones function returns HTML for the options:

$(function() {
    $('#country').on('change', function() {
        $.post("/store/ajax_get_zones", {
            country_id: $('#country').val()
        }, function(e) {
            if (e)
                $("#state").html(e).select2();
        })
    });
});

All you have to do is call .select2() on the element after you update the data.

Start with the default United States:

Then when you change the country the state drop-down changes as well (ajax updated the inner HTML of the original select while still themed to select2
