Try to specify value attributes. And do not forget that in case of radio buttons Model is not supposed to contain boolean value but should contain radio specific values like:

  <input type="radio" name="food" value="beef" [(ngModel)]="myFood"> Beef
  <input type="radio" name="food" value="lamb" [(ngModel)]="myFood"> Lamb
  <input type="radio" name="food" value="fish" [(ngModel)]="myFood"> Fish
