Using "merge" method update data can't get datachange.

Yang model like this:
grouping c-struct {
leaf lf

{ type string; }

}

container test-cs {
container test-c1

{ uses c-struct; }
}

rpc mergeC1 {
input { uses c-struct; }

}

rpc putC1 {
input

{ uses c-struct; }

}
------------------------------------------------------------------------------------
Register test-c1's changes, scope is BASE.

when use tx.put(store, path, t, createMissingParents), data change listener can get data chage event, otherwise use tx.merge(store, path, t, createMissingParents) can't. Test-c1's value in datastore are both changed using two method.
