jQuery doesn't work after post update in UpdatePanel

Another trick or work-around (i think) to make jQuery work right after UpdatePanel server request.

On my example code below, I have a textbox that has class name "datefield" that shows jQuery date picker (date calendar) when you click the textbox.


Javascript:

function load() {
Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
}

function EndRequestHandler() {
 AsyncDone();
}


function AsyncDone() {
 $(".datefield").datepicker();
}


jQuery(document).ready(function ($) {
                        AsyncDone();
                    });




C# codebehind
ScriptManager.RegisterStartupScript(UpdateThis, typeof(UpdatePanel), "EndRequest", "load();", true);
