Creating rows dynamically with default value on row's

I have a row with ngFor that iterates through an array and creates a row with 6 columns, which the first column receives a string from the array. The user can add rows inserting the row name in a text input and pressing a button, the problem is i need the row inside a Form, so i can get the form.value and use it to my database later and i need the first column to have the default value inserted by the user. How can i insert the value string from the ngFor array into the input?

   <form #f="ngForm" (ngSubmit)="postDados(f)" >
    <ion-row class="row header">
    <ion-col class="col">Nervos</ion-col>
    <ion-col class="col">Service Code</ion-col>
    <ion-col class="col">Pay Limit</ion-col>
    <ion-col class="col">Account Number to Use</ion-col>
    <ion-col class="col">Account Number to Use</ion-col>
    <ion-col class="col">Account Number to Use</ion-col>        
  </ion-row>

  <ion-row class="row" *ngFor ="let nervo of nervos">
      <ion-col class="col">
          <ion-input type="text" name="nomeNervo" [(ngModel)]="nomeNervo"></ion-input>                                           
      </ion-col>
      <ion-col class="col">{{nervo.nervoNome2}}</ion-col>
      <ion-col class="col"></ion-col>
      <ion-col class="col"></ion-col>
      <ion-col class="col"></ion-col>
      <ion-col class="col"></ion-col>             
  </ion-row>
</form>
  <ion-row>

    <ion-col col-6>
        <ion-input type="text" [(ngModel)]="nomeNervoNovo" name="nomeNervoNovo"></ion-input> 
    </ion-col>
    <ion-col col-6>
        <button ion-button (click)="pushRow(nomeNervoNovo)" color="danger">
            Inserir
        </button> 
    </ion-col>  
    </ion-row> 

this is the pushRow method

pushRow(nome: string){ 

  this.nervos.push(nome);   

 console.log(this.nervos);

 }

Any ideas? thanks anyway
