var head = document.getElementsByTagName('head')[0];
var script = document.createElement('script');
script.type = 'text/javascript';
script.onreadystatechange = function() {
    // if (this.readyState == 'complete') { callFunctionFromScript(); }
}
script.src = 'path/to/your-script.js';
head.appendChild(script);
