<input ng-model="map['item']">s do not update map items

[vicb]

Consider the following controller

@NgController(
    selector: '[test-controller]',
    publishAs: 'ctrl')
class TestController {
  final indirect = { 'a': true };
  bool a = true;
  var msg = "-";


  void toggle() {
    msg = "a = $a, indirect = ${indirect['a']} -> ";
    indirect['a'] = !indirect['a'];
    a = !a;
    msg += "a = $a, indirect = ${indirect['a']}";
  }
}

and the following html

<ul>
  <li><input type="checkbox" ng-model="ctrl.indirect['a']">= {{ ctrl.indirect['a'] }}</li>
  <li><input type="checkbox" ng-model="ctrl.a">= {{ ctrl.a }}</li>
</ul>
<button ng-click="ctrl.toggle()">Toggle</button>
<p>{{ ctrl.msg }}</p>

The indirect access does not get updated on (un)checking nor toggle

I've investigated this a bit more. The pb does not seem to be on the parser side, as you can see from the unit test. There could be something wrong in the directive ?

I have a fix for this. The issue is that map['key'] was treated as a pure function which is not correct.
