JQuery SELECT filter options based on Radio PRE - selected on load

So, yesterday I posted a question ( Link ) and got the answer I need, but for life I cannot achieve this if the value of the selected is on the load on the body. it only works if the user clicks the radio and then filters the options. Help me please!!!

Function

jQuery.fn.filterOn = function(radio, values) {
    return this.each(function() {
        var select = this;
        var options = [];
        $(select).find('option').each(function() {
            options.push({value: $(this).val(), text: $(this).text()});
        });
        $(select).data('options', options);
        $(radio).click(function() {
            var options = $(select).empty().data('options');
            var haystack = values[$(this).attr('id')];
            $.each(options, function(i) {
                var option = options[i];
                if($.inArray(option.value, haystack) !== -1) {
                    $(select).append(
                    $('<option>').text(option.text).val(option.value)
                    );
                }
            });
        });            
    });
};

      

        
        
        
      

    

How to call

$(function() {
    $('#theOptions').filterOn('input:radio[name=abc123]', {
        'abc': ['a','b','c'],
        '123': ['1','2','3']        
    });
});
