I’m trying to get signalling working in value converters outside of the typical aurelia templating process.

I want to be able to signal my value converter to re-bind (as per [https://aurelia.io/docs/binding/value-converters#signalable-value-converters](https://aurelia.io/docs/binding/value-converters#signalable-value-converters)) but I have a dynamic template and I’m applying the value converter by just getting it from the container and calling `myconverter.toView(params).`

Doing it this way is bypassing the calling of `ValueConverter.prototype.connect` which occurs as part of the template binding process. `ValueConverter.prototype.connect` is where the signals are registered, so my signal is not being picked up…

You can think of value converter as something like a blueprint customize bindings to behave in a certain way. In that sense, it’s kind of odd if you don’t give it any bindings to alter.

What I guess you want to do is to reuse the `toView` method inside a value converter. If so, I think you can extract that bit out and make it a shareable/reusable method for any part of your app.
