Привет, я использую 3 поля ввода внутри одного элемента <div>. Я хочу 3 значения полей ввода при одном вызове функции.

<div class="col-md-6" (change)="calculateDob()">
    <input type="number" id='years' placeholder="Years" [(ngModel)]="ageYears" formControlName="years">
	<input type="number" id='months' placeholder="Months" [(ngModel)]="ageMonths" formControlName="months">
	<input type="number"  id='days' placeholder="Days" [(ngModel)]="ageDays" formControlName="days">
</div>	

<div class="col-md-6">
<input type="date" formControlName="dateOfBirth" [(ngModel)]="setDateOfBirth" disabled>
 </div>     

<div class="col-md-6" (change)="calculateDob($event.target.id,$event.target.value)">
    <input type="number" id='years' placeholder="Years" [(ngModel)]="ageYears" formControlName="years">
	<input type="number" id='months' placeholder="Months" [(ngModel)]="ageMonths" formControlName="months">
	<input type="number"  id='days' placeholder="Days" [(ngModel)]="ageDays" formControlName="days">
</div>	

<div class="col-md-6">
<input type="date" formControlName="dateOfBirth" [(ngModel)]="setDateOfBirth" disabled>
 </div>                                                              
                                                            



calculateDob(total,val){
        if(total==='years'){
            this.ageYears = val;
        }else if(total==='months'){
            this.ageMonths = val;
        }else{
            this.ageDays = val;
        }
        this.birthDay = moment().subtract(this.ageYears, 'years').subtract(this.ageMonths, 'months').subtract(this.ageDays , 'days');
        this.createPatientForm.controls.dateOfBirth.setValue(moment(this.birthDay).tz(this.orgTimeZone).format("YYYY-MM-DD"));
        if(!this.ageYears && !this.ageMonths && !this.ageDays){
            this.setDateOfBirth = null;
        }
    }
