Add and remove fix

[OscarDeDios]

PR Details

Add and remove doesn't clean the checkboxes after remove elements.

The new angular 17 @for {} in templates needs a "track" field with a key element of the array for performance. add and remove is an abstract class then the key element should be set in each use of the component then is a breaking change, it would have to review all the uses of the component. The use of index as a track only works if the list doesn't change.

Then in this case is better to use the traditional *ngFor
