Vb.net, javascript issue including strict mode

Question

I have a VB.net application that I am trying to integrate with the previous deverlopers code. The code takes a zipcode and returns a list of stores along with their location on the google map canvas.

The process works great, with one exception.

I get the following error

JavaScript runtime error JavaScript: access to the 'caller' property of a function or argument is not allowed in strict mode.

I isolated the culprit from

__doPostBack('userControlSearchResults_results', LatLng);

What is inside

function Sys$WebForms$PageRequestManager$_doPostBack(eventTarget, eventArgument) {
        var event = window.event;
        if (!event) {
            var caller = arguments.callee ? arguments.callee.caller : null;
            if (caller) {
                var recursionLimit = 30;
                while (caller.arguments.callee.caller && --recursionLimit) {
                    caller = caller.arguments.callee.caller; // ERRORS HERE
                }
                event = (recursionLimit && caller.arguments.length) ? caller.arguments[0] : null;
            }
        }
    ...

My first inclination was to create window.event so that it would pass an if (!) Event and move on. Since there are other times, we call __doPostback in the code, and it succeeds.

However, since my JavaScript is limited, I either do it wrong or have to find a different approach.

__ doPostback javascript

function CompleteSearch(returnedLatLng) {

    if (returnedLatLng != '') {
        alert("dopostback here2- this is where it breaks");
        __doPostBack('ucSearchResults_udpResults', returnedLatLng);
        if (document.getElementById("sidebar_search")) { document.getElementById("sidebar_search").style.display = "none" };
        if (document.getElementById("sidebar_login")) { document.getElementById("sidebar_login").style.display = "none" };
        if (document.getElementById("promo1")) { document.getElementById("promo1").style.display = "none" };
        document.getElementById("sidebar_results").style.display = "block";
        //document.getElementById("sidebar_results").style.display = "none";
    }
    return false;
}
