Reset button does not reset Select2 fields

[vercotux]

Within a form a should reset all fields, but leaves Select2's untouched.

This piece of code solves the problem:

    $("form button[type=reset]").on("click",function(){
        if (form = $(this).closest("form")) {
            $(".select2-container",form).select2("data", null);
        }
    });
