Like many question I have seen the jQuery document.ready works in the web-part during editing but not after I save the page. I found this code on SO and thought I run a couple of test to see what was happening, I added a couple of alert boxes to see how jQuery was being loaded. to my surprise the script section is never called? below is how I have my setup any help would be great. I'm using SharePoint 365 2013

}
function getScript(url, success) {
    var script     = document.createElement('script');
         script.src = url;
    var head = document.getElementsByTagName('head')[0],
    done = false;
    // Attach handlers for all browsers
    script.onload = script.onreadystatechange = function() {
        if (!done && (!this.readyState || this.readyState == 'loaded' || this.readyState == 'complete')) {
        done = true;
            // callback function provided as param
            success();
            script.onload = script.onreadystatechange = null;

    } else {

        fancyCode();
