title: click event doesn't work, "co.console.log() is not a function"
body: <p>I've been trying to get a button to work to bring up a page, passing an object in the parameters, but for some reason, it gives me the error </p>
  
  <blockquote>
    <p>"co. is not a function."</p>
  </blockquote>
  
  <p>I don't know what the problem is because it gives me the same error when I try to use <code>alert</code> or <code>console.log</code>, or anything.</p>
  
  <p>page <strong>HTML</strong>:</p>
  
  <pre><code>&lt;ion-header&gt;
  
     &lt;ion-navbar&gt;
         &lt;ion-title&gt;SearchResults&lt;/ion-title&gt;
     &lt;/ion-navbar&gt;
  
  &lt;/ion-header&gt;
  
  
  &lt;ion-content padding&gt;
      &lt;ion-list&gt;
          &lt;ion-item *ngFor= "let item of resultArray;"&gt;
              &lt;img src={{item.thumbnail}} /&gt;
              &lt;p&gt;{{item.title}}&lt;/p&gt;
              &lt;button bookDetail (click)="console.log(\"Even some text, please?\")"&gt;DETAIL&lt;/button&gt;
          &lt;/ion-item&gt;
      &lt;/ion-list&gt;
  &lt;/ion-content&gt;
  </code></pre>
