Button that communicates with document inside of an iframe

Question

I'm running a WebGL application within an iframe using embedded html content.  Sofar this works great, but I'm looking to modify an action on the webgl application using a button from indesign.  I've set a javascript sendmessage on the button itself, but this cannot communicate within the iframe.  What would be the best approach for communicating the two?
