Change in the model doesn't affect the DOM Checkbox AngularJS

I am using a checkbox binded to a $scope variable in AngularJS. My code is something like:

<input type="checkbox" ng-model="value.selected"> and I have an object in my controller $scope.value which has the selected property. The changes in the DOM i.e. clicking the checkbox changes the values of the selected property in the value object but the vice versa, i.e. if I change the selected property in the controller it doesn't change the DOM checkbox. Any suggestions or workarounds would be welcome.
