Pop up will display after removing cookies

Question

We have custom button "Save design" in product view page , once guest user clicked on that, it will display pop up as below, but after sometime, onclick button will not display pop up box, but once we delete cookies from browser, than pop up will display again.

In Private window also pop up will display initially, after some time same issue.

    <button onclick="return setproductlogin(\'<?php echo  
    Mage::registry("current_product")->getId()?>\', event);setrequestlogin();"  
     id="submit-editorApply-{{rand}}" >SAVE DESIGN</button>

script

function setproductlogin(pid, event)
{
event.preventDefault();
document.getElementById("likeproduct_id").value=pid;
jQuery("#productlistlogin").trigger("click");
return false;
}   

Browser cookies

Edit

when I delete var/session folder also issue is still there, pop up will work only after removing cookies from Browser
