wire:click "Magewire component {name} could not be found"

[ithuis]

I have setup the most basis magewire component with 1 test function.
i included it in my catalog_product_view_grouped.xml in the "product.detail.page" referenceblock.

The component load's fine, the mount function also gets called.
But when i wire:click="test" i get the response

{"message":"Magewire component "magewire.test" could not be found","code":404}
