Application Development Software

Good Day,

I add some javascript code in bundle.js file within the following path: domain_home\ucm\cs\weblayout\resources\bundle.js .
the changes are reflected fine on the UCM, but once the UCM Server restated the changes are gone and the file revert back as is; without my changes.

the code that i want to add is:

if ((typeof Range !== 'undefined') && !Range.prototype.createContextualFragment) {
Range.prototype.createContextualFragment = function(html) {
var frag = document.createDocumentFragment();
var div = document.createElement('div');
frag.appendChild(div);
div.outerHTML = html;
return frag;
};
}

i want to add it because i have a javascript error like this: Object doesn't support property or method 'createContextualFragment', this erro occured when the used version of Internet Explorer is V.9. ; no javascript errors appears on Version 8. when i add this piece of javascript to the bundle.js file, it the error is gone and everything goes fine, but as i said earlier after restarting the UCM the added javascript code is gone and disappear from the bundle.js file.

For that reason i want to ask, is there is a way to keep my code and stay as is even after restarting? Or is the file uploaded on restart from another path?

Any Suggestions?
