Capture ionic checkbox event in angular directive

ionic-v1
1

I have a directive that is used in many places in my app and when I toggle the checkbox the model is not updated and added to the model object that will be sent back to the server.

I am new to directives and wondered if this would be captured using the link part of the directive?

angular.module('mobile')
.directive('rhConductors', function(){
  return {
    restrict: 'EA',
    scope:{
      model:'=',
      form:'='
    },
    templateUrl:'common/rhConductors.html'
  }
})

Does anybody have some starting code for me please.

<li class="item">
  <label class="item item-toggle">
    Verified
    <label class="toggle toggle-success">
      <input type="checkbox"
             data-ng-model="model.condMEVerified">
      <div class="track">
        <div class="handle"></div>
      </div>
    </label>
  </label>
</li>
