Ionic2: ion-input Issue with label not floating up when type is a number and value is 0

If you have an ion-input element with type=“number”. When the model changes to zero, the label does not float up.

I expect the label to float up.

Steps to reproduce:

1. Click on Calculate button
2. A zero is populated in the input
3. The label and the input are on top of each other.

    <form [ngFormModel]="weightForm" novalidate>
      <ion-item>
        <ion-label floating>Weight</ion-label>
        <ion-input type="number" ngControl="weight" [(ngModel)]="weightModel"></ion-input>
      </ion-item>
      <button secondary (click)="calculateWeight()">Calculate</button>
    </form>

Here is the plunker that demonstrates the issue:
