Configuration of caches is never propagated to another nodes, it's up to you to have it in sync (or with compatible differences only, e.g. different capacity factor). With different numOwners on different nodes, it won't work.
However, you can use Distributed Execution Framework (see Infinispan User Guide) to execute your code on all nodes.
Let me also add, that in server, when using domain mode, changes applied to the configuration are propagated to all nodes through the domain controller mechanism.
