title: Knockout Dropdown Replace on item
body: <p>The data I’m receiving back has a null element in some cases.</p>
  
  <p>The issue is with the binding, I was wondering if I could do a replace however I get an error: </p>
  
  <blockquote>
    <p>Uncaught TypeError: item.FullAddress(...).</p>
    
    <p>Replace is not a function</p>
  </blockquote>
  
  <p>Is there another way to do this?</p>
  
  <pre><code>optionsText: function(item) { return item.FullAddress().Replace(', , ', ', ') }
  </code></pre>
  
  <p>Thanks in advance</p>
