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.
