A function expression can have an optional name after the function keyword. The scope of this name is just the function body, and allows it to be called recursively:

exports.function = {
    my_func: function this_func(a) {
        this_func(a);
    }
}

You can also use its full name:

exports.function = {
    my_func: function(a) {
        exports.function.my_func(a);
    }
}

This is not quite ok as a standard, but you can easily achieve this like:

var foo = function(a) {
    foo(a);
}
exports.functions = {my_func: foo};

Your code does not work because in this case the hoisting is not done ok(well it's done ok) but not for what you need.
