There are number of articles on internet that talk about the fix for the innerHTML issues in IE. some are

None of these work when you try to insert javascript into the <script> tags. Thats because all these solutions talk about using a wrapper <div> for the content and it won’t work if you are trying to insert or modifiy the javascript inside the <script> tags.
The solution is instead of using ‘innerHTML’, use ‘text’ property.
var script = document.createElement('script');
script.type = 'text/javascript';
// IE doesn't support innerHTML, fails, and uses .text instead
try {
script.innerHTML = code;
} catch(e){
script.text = code;
}
document.getElementsByTagName('head')[0].appendChild(script);
