title: Got interpolation ({{}}) where expression was expected with angular
body: <p>I get error on my code with angular 6</p>
  
  <pre><code>&lt;span *ngFor="let tag of item.payload.doc.data().TAGS" &gt; 
                      &lt;button class="nav-link active" (click)="searchByTags('{{tag}}')" &gt;{{tag}},&lt;/button&gt;
                  &lt;/span&gt;
  </code></pre>
  
  <p>I want to have dynamic {{tag}} into searchByTags function but it gives me next error:</p>
  
  <pre><code>Parser Error: Got interpolation ({{}}) where expression was expected at column 14 in [searchByTags('{{tag}}')] in ng:///AppModule/HomeComponent.html@76:56 ("et tag of item.payload.doc.data().TAGS" &gt; 
                      &lt;button class="nav-link active" [ERROR -&gt;](click)="searchByTags('{{tag}}')" &gt;{{tag}},&lt;/button&gt;
                  &lt;/span&gt;
