I thought maybe this was an asynchronous problem or something similar, so I
modified the util.js to do this:
function do Post(callback, data) {
$.post(callback, data).then(doSuccess, doFail);
function doSuccess(data) { alert('Success!'); }
function doFail(data) { alert('Failed!'); }
}
But it didn't solve the problem.
