How to handle onChange with Angular Schema Form Checkbox boolean?
<p>I can't seem to get this onChange event to fire. I have added the method to the code as per the documentation but nothing is happening.</p>

<pre><code> $scope.schema = {
"type": "object",
"title": "Comment",
"properties": {
  "comment": {
    "type": "array",
    "items": {
      "type": "object",
      "properties": {
        "name": {
          "type": "boolean",
          "title": "Name"
        },
        "eligible": {
          "type": "boolean",
          "title": "Eligible for awesome things"
        },
        "code": {
          "type":"boolean",
          "title": "The Code"
        }
      }
    }
  },
  "comment2": {
    "type": "boolean",
    "title": "Name"
  }
},
"required": [
  "comment"
]
};


$scope.form = [
{
  key: "comment",
  onChange: function(model, form){
    console.log('got there though');
  }
},
{
 type: "boolean",
 onChange: function(model, form){
   console.log('this');
 }
},
{
  type: "submit",
  title: "Save"
}
];

$scope.model = {};
</code></pre>
