Can't use ngChange in ngRepeat - Angularjs

I am using ngRepeat to generate a fieldset of checkboxes.

I do this as follows:

<fieldset id="country_select" ng-controller="CountriesListController">
        <span ng-repeat="country in countries">
          <label>
            <input type="checkbox" id="country.name" ng-change="locationAdd(country.name)">
            {{country.name}}
          </label><br/>
        </span>
</fieldset>

However for some reason adding the ngChange directive to my checkbox causes my ng-repeat output to display only one checkbox as follows:

checkbox {{country.name}}

When I change ngChange to ngClick my ngRepeat loop works.

So my question is: Why does ngChange not work with ngRepeat but ngClick does when inserted into my checkbox input
