Cannot reload AD by clearing and recreating new AD div

[AlanLoyc]

Hi,

In my page my AD is loaded normally upon entering, but when I try to reload it, sometimes it will fail and the AD cannot be displayed. I reload with the following script:

function reloadAD() {
    $('#output').html('<div class="adunit" data-adunit="'+adunitID+'" data-dimensions="'+dimensions+'">Ad could not be loaded.</div>');
    $.dfp(networkID);
}

And the script is triggered by a button I inserted as simply as:
<button type="button" onclick="reloadAD()">Reload AD</button>

I inserted the code segments above into the test page cloned from: http://coop182.github.io/jquery.dfp.js/dfptests/test.html?google_console=1&networkID=15572793&adunitID=Leader&dimensions=728x90

It loads without problem through loading it with pressing the "Submit" button, but as I inserted the code above, loads the AD with "Submit", and then reload it with the "Reload AD" button, it will fail after certain tries.

Thanks!
