How can I set a RadioButton to invoke an action, like a Button can?

Question

In Mathematica one can create a Button which, when clicked, invokes an action. For example...

action[dog_] := take dog for a walk;

Button["Click here to take fido for a walk",action[fido]];

...will call the action action[fido] when the button is clicked. However, I cannot seem to find how to similarly invoke an action when a RadioButton has been called. For example...

action[dog_] := take dog for a walk;

RadioButton[dog,action[fido]]

...will set the value of dog to action[fido], not simply call the action action[fido] like the button does. Is there a way to invoke an action when a RadioButton is clicked?

Answer 1

Not sure if it is what you are after:

action[dog_] := Print@StringForm["take dog no.`` for a walk", dog];

RadioButtonBar[Dynamic[dog, (dog = #; action[dog]) &], {1, 2, 3}]
