Detecting change in linked field

[ermouth]

listen to changes

Actually you are listening to the change event, which is not fired this case. It is only fired on direct user interactions, according to https://developer.mozilla.org/en-US/docs/Web/Events/change.

So to track changes from both fields you better add third field, say, <div id="alerter"></div>, and use it as a collector, which may call external code. Please note it will be activated multiple times.

{
  "#name": {
    bind: "name", 
    watch: "#name2"
  },
  "#name2": {
    bind: "name", 
    watch: "#name"
  },
  '#alerter':{
    bind: function(d,v){
      if(v==null) console.log('Name is '+d.name)
    },
    watch:['#name','#name2']
  }
}

Hope it helps.
