Dynamically Load From A File With A Click Handler?

I'm trying to dynamically load javascript from a file with a click handler.

The code is for a class function.

I'm instantiating an instance of the class from the click handler.

It doesn't work the first time I call the "constructor" function, but it does work the second time.

If I put in a call to the "alert" method, it works the first time.

From this, it would be logical to conclude that the code being loaded isn't being given time enough to load and be implanted within the DOM structure for the page.

How can I get the click handler to wait for the code to get established?

What follows is the code for the method that inserts the tag to load the javascript:

Code:
function load_js_code_from_file (js_code_file)
{
var form_ref = document.getElementById ("theForm1");
var new_js_node = document.createElement ("script");

[Code]....
