Sending emeritus form data to POST request

[Craig Russell]

So I have now added some data to the "rescind emeritus request" button [1].
This data is the file name from the emeritus_request, and it is also now data 
available to the submit function. (If there is a better way to do this, please 
let me know.)

The data is read in the submit function [2]. But it doesn't work. What is the 
right way to send additional data fields in the POST request? I have verified 
via the console log that the data (emeritus_file_name) is proper, but I get an 
exception trying to put it into the formData. 
TypeError: undefined is not an object (evaluating 'formData.push') line 371

What I'm trying to do is to have the file name available to the memstat.json.rb 
file that handles the POST request. Is the entire committer transmitted on the 
POST, or just the few changed fields?

Thanks,
Craig
