Unable to access function parent with event

This is from my parent component html.

       <div class="section graph ltr">
                        <campaign-graph
                            (getLeads)="getLeadsForCampaign($event)"
                            [campaign]="campaign"
                            [leads]="campaign.leadTotal"
                            [leadsCount]="leadsSum"
                            [openLeadsCount]="openLeadsCountForCampaign"
                            [averagePosition]="averagePositionForCampaign"
                            [difference1stPlace]="difference1stPlaceForCampaign"
                        ></campaign-graph>
                    </div>

"campaign-graph" is the child, all of the field are getting fine in the child, but I am not entering "getLeadsForCampaign" on the parent. why? Parent: getLeadsForCampaign(campagin) { this.toChild = campagin; if (this.leadsSum > 0) { this.averagePositionForCampaign = this.leadsSum; } }

child:

     @Input() leads: number;
        @Input() leadsCount: number;
        @Input() openLeadsCount: number;
        @Input() averagePosition: number;
        @Input() difference1stPlace: number;
        @Input() campaign: Campaign;
        @Output() getLeads: EventEmitter<Campaign> = new EventEmitter<Campaign>();
        current: Campaign;
        constructor(
            public moneyPipeC: RubikShekelPipe,
            private currentRouterC: ActivatedRoute,
            private readonly _exportServiceC: ExportService,
            private readonly _apiC: BestiapiService,
            _utilsC: UtilitiesService,
            private translate: TranslateService,
            private http: HttpClient,
            private authC: AuthService
        ) {
            super(currentRouterC, moneyPipeC, _exportServiceC);
        }

        fromParent(Campaign) {
            this.getLeads.emit(Campaign);
        }

        ngOnInit() {
            this.fromParent(this.current);
            this.dayFilter = EditField.optionFieldBuilder('agencies', this.translate.instant('CAMPAIGNS.FILTER_DAYS.TITLE'), []);

        }
