Angular2 ngModel inside ngFor (Data not binding on input)

by

When creating multiple ngModel controls inside ngFor loop make sure to give each control unique name:

<form name="userForm">
<table>
<tr *ngFor="let item of itemList; let in = index">
  <td><input type="text" name="lastname-{{in}}" [(ngModel)]="item.lastname"></td>
  <td><input type="text" name="middlename-{{in}}" [(ngModel)]="item.middlename"></td>
</tr>
</table>
</form>
