    You need to use the response in the $.ajax success function. This response object should be your json object and can therefore easily be accessed via the specified properties category_name and category_id.

    $.ajax({
        // ...
        success: function(response){
            // do something with the json response! E.g. generate a new list item and append it to the list.
            var categoryList = $('#category');
            var category;
            for(var i = 0, len = response.length; i < len; i++){
                category = response[i];
                categoryList.append($('<li>').attr('id', category.category_id).html(category.category_name));
            }
        },
    });
