Checkbox not binding to scope in angularjs

Question

I am trying to bind a checkbox to scope using ng-model. The checkbox's initial state corresponds to the scope model just fine, but when I check/uncheck the checkbox, the model does not change. Some things to note is that the template is dynamically loaded at runtime using ng-include

app.controller "OrdersController", ($scope, $http, $location, $state, $stateParams, Order) ->    $scope.billing_is_shipping = false   $scope.bind_billing_to_shipping = ->     console.log $scope.billing_is_shipping   <input type="checkbox" ng-model="billing_is_shipping"/> 

When I check the box the console logs false, when I uncheck the box, the console again logs false. I also have an order model on the scope, and if I change the checkbox's model to be order.billing_is_shipping, it works fine

I struggled with this problem for a while. What worked was to bind the input to an object instead of a primitive.

<!-- Partial --> <input type="checkbox" ng-model="someObject.someProperty"> Check Me!  // Controller $scope.someObject.someProperty = false

If the template is loaded using ng-include, you need to use $parent to access the model defined in the parent scope since ng-include if you want to update by clicking on the checkbox.

<div ng-app ng-controller="Ctrl">     <div ng-include src="'template.html'"></div> </div>  <script type="text/ng-template" id="template.html">     <input type="checkbox" ng-model="$parent.billing_is_shipping" ng-change="checked()"/> </script>  function Ctrl($scope) {     $scope.billing_is_shipping = true;      $scope.checked = function(){         console.log($scope.billing_is_shipping);     } }
