Keeping the logic of a component in itself is what component-based approach is about. A click listener on a component or its sub-element is very personal and private to a component.
Mixins
But.. let’s say you have a situation where you have the same exact logic that needs to be executed on-click on multiple components, the answer will be to use mixins. Store is not the place to do it. This holds and is true for any case where you need to ‘share reusable functionalities’.
Apart from providing flexibility, mixins have a number of benefits, for instance, you can take advantage of the option merging rules within mixins to override the onClick() method described in a mixin to cater for a special case within one of the components, but continue to use the rest of the common logic the mixin contains.
Note: Be careful though, Hook functions with the same name are instead merged into an array so that all of them will be called. Mixin hooks will be called before the component’s own hooks.

As a great real world example check out this repository: https://github.com/buefy/buefy. Its a UI components library that is built with Vuejs. You can find many more examples and best practices in such open source repositories and these are always a great reference point for writing better code.
