Task Assignees - Change cell content using ajax


I need to implement the “Task Assignees” feature, which will display the user logos next to the user names assigned to a specific task,
for this it is more convenient to me to fetch html from the server and append it to the specific cell.

I tried to use the onrender column: function (article, node) with an ajax call inside, but it is triggered every time the Windows is resized etc., and makes many unnecessary http calls.

Is there a more convenient way to fulfill my need?


I just got an example, if someone else need this also here it is: https://snippet.dhtmlx.com/luyiubhp
