Try this:

Add one hidden option and on selection of option take the text of value and insert into hidden option and make it selected forcefully everytime.

$('#selectbox1').on('change', function(){                                           
    var option = $(this).find('option:selected');
    $('.hide').text(option.val()).val(option.val());    
    $('.hide').data('value', option.text());
    $('.hide').attr('selected', true);        
});

To get the selected option value and text, you can this:

$(this).find('option:selected').val();
$(this).find('option:selected').data('value');
