I am creating HTML DOM elements using Javascript (yes, I know it's nasty).  

I can get the select element created but I cannot add an onchange property.

Example:

```
var sel = document.createElement('select');
sel.id = 'someID';
sel.title = 'Some title';
sel.style.fontWeight = 'bold';
sel.size = 1;

```

Once I have added the options and have done a  

`document.getElementById('someOtherID').appendChild(sel);`  

I get my select element.

What I want to do is, at A above, add:  

`sel.onChange = 'someJavascriptFunction()';`  

but it doesn't like it.

Should I be thinking outside of the square? Which one?
