"onChange" events?

[jeron-diovis]

All existing events are triggered when value "may have been updated". How do I know that value is actually changed? For now I'm tracking previous value myself and compare values on "data" event, this is extremely inconvenient.

I had the same problem, but i used this:

  rome(document.querySelector('#date').on('data', function (value) {
    console.log(value);
  });

I find ,the correct statement is blow: rome(document.querySelector('#date')).on('data', function (value) {console.log(value);}); simple var test=rome(dom_id); test.on('data',function (d) { alert(d); }) `
