jquery.each multidimensional array

var array1 = {};

array1['one'] = new Array();
array1['one']['data'] = 'some text';
array1['one']['two'] = new Array();
array1['one']['two']['three'] = new Array();
array1['one']['two']['three']['data'] = 'some other text';

$.each(array1, function(key1, value1){
    $.each(value1['two']['three'], function(key1, value1){
        document.write('test');
    }
});

everything works, except it doesnt get to the document.write. Anyone an idea why?
