That looks a lot like Python syntax... :)

sources() is just an accessor though, instead use setData(...) or 
addSource(...) if you want to put data into your engine.

Also useful, in order to debug in your code:

if (dataSource["mysource"]) { print(dataSource["mysource"]); }

or if (typeof(dataSource["mySource"]) ...

You can also check what you're connected to:

or print(dataSource.connectedSources)

In your DataSource:

DataSource {
    id: ds
         [...]
        onNewData: {
                print(source, data);
        }
}

this should make it a bit easier to do basic print-level debugging.
