Inflector example seems to be broken

in the app.js

function InflectorCtrl($scope) {
    $scope.inflectorText = 'Here Is my_phoneNumber';
    $scope.inflectorType = 'humanize';
}

in the demo page there are options for
     Humanize (Default)
     Underscore
     Variable

but nothing happens, no errors are thrown that I can see.
