Bind select options in KnockoutJS

I initialized an array with 3 values and later I try to add one more item to the array. It fails and I got an exception says "Uncaught ReferenceError: viewModel is not defined ". Any idea why is this?

var ViewModel = {
        // These are the initial options
        availableCountries: ko.observableArray(['France', 'Germany', 'Spain'])
    };
    viewModel.availableCountries.push('China');

    ko.applyBindings(ViewModel);

JavaScript is case sensitive, so you need to capitalize your variables consistently everywhere they're used. To fix the error, you can make the "v" uppercase in the second statement:

ViewModel.availableCountries.push('China');

Or you can make the "V" lowercase in the first and third statements.
