title: Method Call Syntax in CoffeeScript
body: <p>I'm new to CoffeeScript, and I seem to be having trouble with the syntax for calling methods.</p>
  
  <p>Here's the Card model:</p>
  
  <pre><code>class exports.Card extends Backbone.Model
    defaults:
      pip:   '4'
      suit:  '♠'
      color: 'b'
  
    rows: -&gt;
      rows =
        '4': [2, 0, 2]
      rows[@pip]
  </code></pre>
  
  <p>And the relevant portion of the template:</p>
  
  <pre><code>&lt;ul class="col cols-&lt;%= @card.rows()[0] %&gt;"&gt;
  </code></pre>
  
  <p>which is giving me the error <code>Uncaught TypeError: Object #&lt;Object&gt; has no method 'rows'</code></p>
  
  <p>Specifically, I'm wondering if I'm using incorrect syntax for the rows method of Card or if I'm just misunderstanding something. Thanks in advance!</p>
  
  <p><strong>Update:</strong></p>
  
  <p>For some reason, <code>@card.property</code> always works fine, but <code>@card.any_method()</code> never does. I've gotten around this at the moment by using properties, but I'd love it if someone was able to explain this behavior. Thanks again!</p>
  
  <p><strong>Update 2:</strong></p>
  
  <p>I'm using <a href="http://brunchwithcoffee.com" rel="nofollow">http://brunchwithcoffee.com</a> if it's a help to anyone, and here's the <code>main.coffee</code> file to show how the <code>@card</code> instance is being created and passed to the view.</p>
  
  <pre><code>window.app = {}
  app.routers = {}
  app.models = {}
  app.collections = {}
  app.views = {}
  
  Card = require('models/card_model').Card
  MainRouter = require('routers/main_router').MainRouter
  HomeView = require('views/home_view').HomeView
  CardView = require('views/card_view').CardView
  
  # app bootstrapping on document ready
  $(document).ready -&gt;
    app.initialize = -&gt;
      app.routers.main = new MainRouter()
      app.views.home = new HomeView()
      app.views.card = new CardView(model: new Card(color: 'r', suit: '♥', pip: '7'))
      app.routers.main.navigate 'home', true if Backbone.history.getFragment() is ''
    app.initialize()
    Backbone.history.start()
  </code></pre>
