How to attach listener to WAB geoprocessing widget drop down

[MichaelMitchell5]

I'm modifying geoprocessing Widget.js to create cascading drop down menus.  I'm attempting to attach a listener to one of the menus.  I'm doing this towards the bottom of the _createInputNode method.

if(param.name == "Habitat_type"){

        console.log("attach listener");

        on(inputEditor, "change", lang.hitch(this, this.selectChange));

 }

"attach listener" shows in the console but when I change the drop down selection the selectChange method doesn't run.

Thanks for the help!

I changed inputEditor to inputEditor.gEditor and it worked.  I found this by looking at editorManager.js and found the spot where editorName === 'Select' then saw o.gEditor.  After debugging the trouble line in the code I saw that the inputEditor object had a gEditor parameter.  Forgive the terminology if it's wrong.
