That work fine in Ajax call back to update select from JSON object

function UpdateList() {
    var lsUrl = '@Url.Action("Action", "Controller")';

    $.get(lsUrl, function (opdata) {

        $.each(opdata, function (key, value) {
            $('#myselect').append('' + value + '');
        });
    });
