IE11 Ajax调用不起作用

Question

When I am calling requestwidgets function under document.ready it is successfully getting called and call to handler is made. But when the same function i am calling from some function it is not getting called Note: This is only happening in IE11 browser Below is the code

function CreateNewWidget() {
    $elementName = $("#ux_widget_name").val();
    $elementType = $("#ux_widget_type_dll").val();

    $url = '?request=newelement&elementtype=' + $elementType + '&appguid=' + appguid + '&elementname=' + $elementName;

    $.get($url, function (data) {
        if (data == "True") {
            RequestWidgets();
        }
        setTimeout("$.fn.slickBox.close()", 3000);
    });

}

var elements = Array();

function RequestWidgets() {
    $.get('/shared/test2.ashx?request=getelements&appguid=' + appguid, function (data) {
        xmlDoc = $.parseXML(data);
        elements = Array();
        RenderElements(elements);
    });
}
