 function embed() {
     window.func = null;

     var mydiv =document.getElementById("myDIV");
     mydiv.innerHTML="Replaced!!";

 var script = document.createElement('script');
 script.type = "text/javascript";
 script.innerHTML = "(" + embed + ")()";
 document.getElementsByTagName('head')[0].appendChild(script);
