call time difference not showing after status change or after save/update

[elbowprogrammer]

I created field in Call entity named time_call. I'm trying the set the date completed and time_call when the status has been changed to "Held". Not sure how to do it on the server side, so I tried to do it on the client side (client/modules/crm/src/views/call/detail.js) in the setup function. The fields are changing when the field is held, but it is not shown when I change the status or even after I update/save it. I would have to update/save, get out of the Call item, then go back in it just to see the fields changed. My code is below. This issue to resolved is on a time clock. I would very appreciate a quick response. Also is there a isfieldchanged on the client side, or do I just use model.hasChange([attribute])?

             if(this.getAcl().checkModel(this.model,'edit')){
          //      if(['Held'].indexOf(this.model.get('status')) != -1){
                if(this.model.get('status') == "Held"){
                    //  var diff = (moment(this.model.get('dateCompleted')).unix() - moment(this.model.get('dateStart')).unix()) / 3600;
                    var dateEnd = moment(this.model.get('dateEnd')).unix();
                    var dateStart = moment(this.model.get('dateStart')).unix();
                    var diff = Math.abs(dateEnd) - Math.abs(dateStart);
                    var time_call = Math.ceil((Math.floor(diff) / 3600) * 100) / 100;
   
  
                    this.model.save({
                        'dateCompleted': this.getDateTime().getNow(),
                        'time_call': time_call
                    });
                }
                else{
                    this.model.save({
                        'dateCompleted':null,
                        'time_call':null
                    });
                }
            }

Check out how it's done in the Tasks code

    protected function beforeSave(Entity $entity, array $options = array())
    {
        parent::beforeSave($entity, $options);
        if ($entity->isFieldChanged('status')) {
            if ($entity->get('status') == 'Completed') {
                $entity->set('dateCompleted', date('Y-m-d H:i:s'));
            } else {
                $entity->set('dateCompleted', null);
            }
        }

This can be found in the \application\Espo\Modules\Crm\Repositories\Task.ph p file. You should be able to do something similar when the status is Held.

Manage to get it to work. I knew of the code for Task entity, but I was hoping to do it on the client slide instead. I manage to get it to work with the Task code for the datecompleted and the time diff. For future reference, is it possible to do it on the client side?
