How correctly bind data to radio buttons in Angular2?

This works in my case. I removed [(ngModel)]

<div class="radio">
<label>
    <input type="radio"
           value="1"
           [checked]="model.ForeignCompany.ProfitCode === 1"
           id="point1"
           (change)="onProfitSelectionChange(1)"
           name="ProfitCode"><small>description</small>
</label>
</div>
<div class="radio">
    <label>
        <input type="radio"
               value="2"
               [checked]="model.ForeignCompany.ProfitCode === 2"
               id="point2"
               (change)="onProfitSelectionChange(2)"
               name="ProfitCode"><small>description</small>
    </label>
</div>

and TS method looks like:

onProfitSelectionChange(entry): void {
    this.model.ForeignCompany.ProfitCode = entry;
}
