Bug or Implementation error with ng-if in Ionic?

Question

I created a list where I need to show whether an item has already been read or not, so I check a variable with the ng-if directive. But when the item is opened, and then returns/browses back to the list, there is no change in the list. I noticed that the variable being checked with ng-if is having its value changed, but ng-if does not reevaluate when the view is shown again. ng-if only works when the screen is loaded/reloaded, ie when close and open the app again.

How could you get around this problem?

<ion-item collection-repeat="item in items" 
             ng-click="ctrl.marcaLida(item.id)"                                    
             ui-sref="menu.telaLeitura({idItem:item.id})">

                        <p ng-if="!item.lido_em">o</p>
                        {{item.nome}}

                    </ion-item>
                </ion-list>

I’m using router for navigation.

Checks whether ng-click="ctrl.marcaLida(item.id)" is changing the status of the item opnde they come, bank, localstorage, etc. Why when vc leaves the screen and back it is running the repeat of the items and it is not marked as read
