kubernetes: Replication controller with nodeSelctor conditional doesn't succeed if nodes are labeled after it is submitted

Kubenetes version 1.4.

Replication controller YAML contains:

spec:
   nodeSelector:
      foo: bar
   containers:

kubectl create -f above file.

Realize you’ve forgotten to label nodes or have a typeo, do:

kubectl label nodes <nodename> foo=bar

Expected: rc to notice newly matching nodes and proceed.

What happened: rc did not proceed.

Work around: kubectl delete -f above file and create again, proceeds immediately.
