Im using react , meteor and flow router. How do I redirect once data has been inserted to the database

This is the function I have

```
Meteor.call('insertQuestion', header, content,      
 usernameoremail,date,function(error){
  if(error) {
     show({text: error.reason, pos: 'bottom-left'});
  }
  else {
    show({text: "Your Question Has been posted", pos: 'top-right'}); 
  }
});

```

Which flow router function should I use?
