title: How to use an angularJs filter on items label within ng-options
body: <p>Given a select list loaded with product options, I want the label to be in the format of option name and then price in parenthesis.  So for example:  "Product Option B ($1,432.12)".  My option object has the properties "name" and "price".  Price is numeric, I want it formatted with the currency filter.  How would I do this?  I'm thinking maybe a custom filter that takes a string and numeric value.  Just not sure how I would be able to apply the filter within ng-options.</p>
  
  <p>The following code just displays the name (not price):</p>
  
  <pre><code>&lt;select class="form-control"
          ng-model="selectedOption"
          ng-options="option.name for option in category.options"&gt;&lt;/select&gt; 
  </code></pre>
