title: How to call one custom helper function in another custom helper
body: <p>I want to use one helper function in another helper function. In below code I want to highlight last name if it contains "Finch" word. I have writtern helper class for that. 
  If we use in hbs file then syntax would be {{highlight name}}.
  But how to use it since I have to use it in another helper class.</p>
  
  <p>Below is my code:</p>
  
  <pre><code>  Handlebars.registerHelper('fullName', function(person) {
      return person.firstName + " " + person.lastName;
    });
  
     Handlebars.registerHelper('highlight', function(person) {    
  var item = (person.lastName).replace('Finch', '&lt;span style="color: red"&gt;' 
    + Finch + '&lt;/span&gt;');
  return new Handlebars.SafeString(item); 
    });
  </code></pre>
  
  <p>Here is the working fiddle : <a href="http://jsfiddle.net/wC6JT/4/" rel="nofollow">http://jsfiddle.net/wC6JT/4/</a></p>
  
  <p>Here is the fiddle where "highlight" helper is called.: <a href="http://jsfiddle.net/wC6JT/3/" rel="nofollow">http://jsfiddle.net/wC6JT/3/</a> . This will not produce any results since we will get console errors for person.lastName not recognized in "highlight" register helper.</p>
  
  <p>I want to use "highlight" helper in fullname helper  for person.lastName.
  How can this be acheived.</p>
