title: Can't use *ngIF inside *ngFor : angular2
body: <p>i'm using angular2 and i'im binding data from a service , the probleme is when i'm loading data i should filter it by an id , , this is what i'm supposed to do :</p>
  
  <pre><code>&lt;md-radio-button
          *ngFor="#item of items_list"
          *ngIf="item.id=1"
          value="{{item.value}}" class="{{item.class}}" checked="{{item.checked}}"&gt; {{item.label}}
  &lt;/md-radio-button&gt;
  </code></pre>
  
  <p>and this is the data:</p>
  
  <pre><code>[
    { "id": 1, "value": "Fenêtre" ,"class":"md-primary" ,"label":"Fenêtre" ,"checked":"true"},
    { "id": 2, "value": "Porte Fenêtre" ,"class":"" ,"label":"Porte Fenêtre" }
  
  ]
  </code></pre>
  
  <p>by the way i want just the data with id =1 to be accepted , but  i'm seeing this error:</p>
  
  <pre><code>EXCEPTION: Template parse errors:
  Parser Error: Bindings cannot contain assignments at column 14 in [ngIf item.id=1] in RadioFormesType1Component@10:16 ("
          &lt;md-radio-button
                  *ngFor="#item of items_list"
                  [ERROR -&gt;]*ngIf="item.id=1"
                  value="{{item.value}}" class="{{item.class}}" checked="{{item.check"): RadioFormesType1Component@10:16
  </code></pre>
  
  <p>so any suggestion to use ngif and ngfor together ?</p>
