title: ngModel in select tag - inside ngFor
body: <p>the ngModel in this example is killing my browser. 
  any ideas how to get each table cell ng-model?? (i tried to use (change), and it worked - but changed the selected value)</p>
  
  <pre><code>&lt;tr *ngFor="let step of procSteps; let i = index;  let first = first; let last = 
                                        last; let even = even; let odd = odd;"&gt;
  
                  &lt;td&gt; &lt;p&gt;{{step.position}}&lt;/p&gt; &lt;/td&gt;
  
                  &lt;td&gt; &lt;p&gt;{{step.name}}&lt;/p&gt; &lt;/td&gt;
  
                  &lt;td&gt;
                      &lt;select [(ngModel)]="selectedSystemStep[i]"&gt;
                          &lt;option *ngFor="let system of systemModuleList" 
                                  [value]="system.id"&gt;{{system.name}}&lt;/option&gt;
                      &lt;/select&gt;
                  &lt;/td&gt; 
  &lt;/tr&gt;
  </code></pre>
