How to disable to cache ajax/json?

When you download website with ajax loaded json and displayed, but after adding anything in this json for some time displayed the old data. How to fix? In html there are such tags
<meta http-equiv="Cache-Control" content="no-cache"> 
 <meta http-equiv="Cache-Control" content="private">

The website is something like to-do list, but all users it needs to be one, so is saving on server and need to refresh the page is loaded new data.
