How do I see exposed variables in repeated custom components from another library?

you need to have a unique id for every repeated item in the column, this way it is accesible in the context and you know from where the event is coming.
it’s the same thing with native weweb elements (like inputs) used inside a column/collection list.
here you can find links to two examples with weweb elements, you can adapt them to a custom element as well
