how to clear input helper after action is handled?

I'm using Ember v 1.13.8

I have input helper:

{{input type="text" value=newData action="addNewItem"}}

and action handler:

actions: {
    addNewItem: function(value) {
      this.get('personList').pushObject({name: value});
      this.set('newData', '');
    }
}

As you can see in order to clear input I have variable in controller where I store temporary value. I made input helper dependent on it and this approach works, but I wonder may be there is Ember way of doing this?
