Stache not getting updated

After saving the change into the file, it is not displaying the changes. The stache is not updating automatically.

I do this action as a plugin, to reset all closed_today values overnight.

/**
     * Execute the console command.
     *
     * @return mixed
     */
    public function handle()
    {
        $collections = Entry::whereCollection('CollectionName');

           $collections->each(function($collection) {
               $collection->set('closed_today', false);
               $collection->save();
           });
     }

Is it a bug or do i have to trigger clear:stache. If yes, how to fire the command inside an addon command i have written myself.
