Trigger touch callout on ios/android

I would like to know if there is any possibility to trigger the "Save Image" touch callout on iOS and Android with Javascript. The callout is triggered by a longpress, but even if I try to simulate this, it won't work.

I would like to achieve something likes this:

jQuery('img').openCallout();

So far I tried this:

jQuery: jQuery('img').contextmenu();
jQuery Mobile: jQuery('img').taphold();
