Delay callback until script is added to document?

Question

How can I get the callback to not run until the script is actually appended to the document?

function addScript(filepath, callback){
    if (filepath) {

This tiny script / css loader will do the job https://github.com/rgrove/lazyload/

LazyLoad.js('/foo.js', function () {
  alert('foo.js has been loaded');
});
