javascript - Error: No controller: ngModel

When I add ng-change="reverseOrder=this.checked" to a checkbox, as so:

<input id="reverseOrder" type="checkbox" ng-change="reverseOrder=this.checked"/>

I get the following exception:

Error: No controller: ngModel

I've tried adding ng-model to the inputbox, a div wrapping the entire view and in the <html> tag, this produces an exception liek the following:

Error: Non-assignable model expression:  (<div class="ng-scope" ng-model="">)

What's going on here? I didn't think I needed to explicitly pull in the model. I've read the Angular documentation but am none the wiser.

Thanks in advance.

ngChange requires ngModel directive. But you're using ngChange for the same purpose of ngModel. Just go with:

<input id="reverseOrder" type="checkbox" ng-model="reverseOrder"/>
