get details/images from datagrid view

[zudu]

In a case like this: https://www.jeasyui.com/tutorial/datagrid/datagrid21.php, how can I click and select the image and make it bigger?

Bind a 'click' event on the image, open a dialog to display a bigger image.

yes, that's precisely what I want to do...but I can't find any selector that works with the image. I tried
$(".img").on("click", function() {
//manage the image
});
or, using delegated event handler (because the img is added only after the detail row is shown)
$("body").on( "click", ".img", function() {
  //manage the image
});
None of the above code "clicks" any event...I tried changing the selector, assigning an ID or different class name, but it just doesn't seem to "see" the added row...
