Angular material checkbox - add function to ng-checked

I am using the <md-checkbox> with the 'indeterminate' attribute provided by Angular Material to update an array based on the checkboxes selected. However, the Array is only updated based on ng-click, not on ng-change. Therefore, checking the "Select All" item, will not insert the values into the array.

Consider this codepen.

How can I update the addData function based on ng-change?
