I am looking for the best method of listening for form changes in this form. It loops through an array adding inputs and I will need to know which specific input has changed so I can save the value. I have started playing with FormArray but not sure the best method of going about this. Any help would be appreciated.
<form [formGroup]="form">
<ion-row *ngFor="let subQuestion of question.subQuestions; let i = index;">
<ion-col col-12>
<h5>{{subQuestion.questionText}}</h5>
<ion-item>
<ion-input type="text" placeholder="ex: 100" formControlName="value"></ion-input>
<ion-select interface="popover" formControlName="measurement">
<ion-option *ngFor="let option of subQuestion.options" value="{{option.value}}">{{option.text}}</ion-option>
</ion-select>
</ion-item>
</ion-col>
</ion-row>
</form>
