Missing calling when emit on clean Event

[tfSheol]

Fix missing clean calling with :

ngAfterContentInit() {
        this.addSubscription(SubType.SYSTEM, this.clear.subscribe(() => {
            this.masterForms = [];
            this.data = {};
            this.container.clear();
            this.onError.emit([]);
            this.onValidate.emit(false);
            this.onData.emit({
                data: [],
                form: <FormGroup>{}
            });
            this.subscriptions.filter(sub => sub.type == SubType.DEFAULT).forEach(subscription => {
                if (!subscription.subscription.closed) {
                    subscription.subscription.unsubscribe();
                }
            });
        }));
        this.addSubscription(SubType.SYSTEM, this.render.subscribe(() => this.renderItem()));
        this.addSubscription(SubType.SYSTEM, this.reload.subscribe(() => {
            this.container.clear();
            this.renderItem();
        }));
    }
