DataTable is the most powerful tool to sort data in tables but I still struggle how to handle DataTable cells' content properly by JavaScript. I use Ajax to load data into the table and then I can't find the part of my data in the DOM.
I've created a simple table model of what I want to have done.

I load the test_array.txt file into my table, then I add an additional row (jRow = $('<tr class=user_row>').append). Later I need to modify the "Days" column by JavaScript (document.getElementsByClassName('days')[i].innerHTML = days).
1) The main problem is that I can access through DOM to the first page of my DataTable only (paging: true). Note that the "Days" are not calculated in the second or other pages. Unfortunately, I need a large table, so I can't always use the option paging: false which helps.
2) Is there a smarter option to check the DataTable availability without using setTimeout() function? You can uncomment two alerts in my code to understand better what's going on.
