Weird JS problem

gistfile1.js

(function() {
  var fixedAssetColumns, totalsRowTemplate;

  fixedAssetColumns = [
    {
      name: 'description'
    }, {
      name: 'date'
    }
  ];

  console.log(fixedAssetColumns); // Prints fixedAssetColumns to console (as one would expect)

  totalsRowTemplate = function() {
    return tr(function() {
      // Uncaught ReferenceError: fixedAssetColumns is not defined
      // Weird because this is ultimately nested within the same function scope and should be captured.
      return _.each(fixedAssetColumns, function(col) { 
        return td;
      });
    });
  };

}).call(this);

Was nothing to do with my JS. It was CoffeeKup converting a function back to a string, and reevaluating in different context thus losing the closed-over variables. Thanks for taking the time to look though :)
