title: Issue when implementing multiple cell inputs in Angular2
body: <p>I have a table where each td has an input (like a spreadsheet).</p>
  
  <p>My html template the code as follows:</p>
  
  <pre><code>&lt;tr *ngFor="let project of projects" (click)="onSelect(project)"&gt;
      &lt;th class="panel fixed"&gt;{{project.id}}&lt;/th&gt;
      &lt;th class="panel fixed"&gt;{{project.name}}&lt;/th&gt;
  
      &lt;td *ngFor="let load of projectLoads[project.code]; let d=index" class="cell panel scrolling"&gt;
          &lt;input class="load"  [(ngModel)]="projectLoads[project.code][d]" title="{{project.code+' . '+d}}" /&gt;
      &lt;/td&gt;
  …
  </code></pre>
  
  <p>When I fill one cell in with a number, for example 1, the number is repeated in the next cell.</p>
  
  <p>How it comes?</p>
  
  <p>(Note that there is no ngForm in my current code.)</p>
