How to fire an event when v-model changes?


I'm trying to fire the foo() function with the @click but as you can see, need press the radio button two times to fire the event correctly . Only catch the value the second time that you press...

I want to fire the event without @click only fire the event when v-model (srStatus) changes.

here is my Fiddle:
