After updating to angular 1.8, changes to a object (in this case the
container object) has changed from the click event to the onchange event
for input radio's and checkboxes as described on
https://docs.angularjs.org/guide/migration#-input-radio-and-input-checkbox-
In our scenario this means the container.is_public value is changed
_after_ the ajax call went to the horizon API, effectively not changing it.
This change fixes this, by migrating to the ng-change event for this toggle
