title: Trying to click this button in CasperJS
body: <p>I have the following code:</p>
  
  <pre><code>casper.start("my link here", function() {
      this.click('.btn btn-primary circle right');
  });
  
  casper.run();
  </code></pre>
  
  <p>I am getting the error <code>CasperError: Cannot dispatch mousedown event on nonexistent selector: .btn btn-primary circle right</code></p>
  
  <p>If I inspect the element in chrome it looks like <code>&lt;button class="btn btn-primary circle right" data-reactid=".3.1.0.0.0.1.3.0.0.0.$right" data-label="right" data-action="Pagination" data-search-track="true"&gt;&lt;/button&gt;</code></p>
  
  <p>I can also do <code>console.log(this.getPageContent());</code> and I can see the button in the output.</p>
