I found out how to do this by digging through the LZXReference. It turns
out that all I need to do is define an 'updateData' method on my class
which looks like this:
<method name="updateData">
return _combo.value;
</method>
Pretty simple, actually. Just had to find the right place in the
documentation to figure out what I needed to do.
