Subscribing to onChange jQuery dart

Question

I am trying to listen to the jQuery onchange event in dart as the native onchange event is not firing when using a jQuery date picker.

Here is my current code

js.context.jQuery("#venueDatePicker").on("change", new js.Callback.many((e, data) {
    print("Will be executed");
}));

Here is the error i am getting

malformed type: line 61 pos 63: type 'js.Callback' is not loaded
            js.context.jQuery("#venueDatePicker").on("change", new js.Callback.many((e, data) {

not tested but I think it should be like:

js.context.callMethod(r'$', ["#venueDatePicker"])
    .callMethod('on', ["change", (e, data) {
      print("Will be executed");
    }]);

`js.Callback` was removed. You can directly use Dart Functions. – Alexandre Ardhuin May 16 '14 at 14:18
NoSuchMethodError: method not found: 'callMethod' Receiver: Instance of 'JsObject' Arguments: ["$", Instance(length:1) of '_GrowableList'] – Jake Rote May 16 '14 at 15:30
if your JS code in your question works try `jQuery` instead of `$` – Günter Zöchbauer May 16 '14 at 15:34
i think it means the callMethod method dosent exist for some reason – Jake Rote May 16 '14 at 15:38
Do you have the script tags in your HTML page? see http://stackoverflow.com/questions/19547730 – Günter Zöchbauer May 16 '14 at 15:46
Yes i have all of the required script tags – Jake Rote May 16 '14 at 15:48
maybe this one https://code.google.com/p/dart/issues/detail?id=15065#c11 is related? – Günter Zöchbauer May 16 '14 at 15:50
Yes i have added them – Jake Rote May 16 '14 at 16:23
Are you using `dart:js` or [js package](http://pub.dartlang.org/packages/js) ? The above code snippet assume you are using `dart:js`. – Alexandre Ardhuin May 16 '14 at 20:47
