I hope this helps . Looks like you are almost in the right direction. Please check whether the following fix your problem:
code :
events: {
            'click .pro_list_imgbox': 'loadPic',
            'click li[data-id]': 'detailHandler'
        },

loadPic: function (e) {
            var target = $(e.target),
                pic = target[0].nodeName === 'IMG' ? target : target.find('img');

            if (!pic.data('loadState')) {
                pic.attr('src', pic[0].src += '?t' + new Date().getTime());
            }
           //this return statement will not allow the event to propagate to the parent element.
            return false;

        },

detailHandler: function (e) {
            alert('haha');
        },

fetchRelated after fetch using Backbone.Relational with Backbone.Marionette and Backbone.ioSync

I wish did fix the issue. Marionette now has Marionette.Async that makes it easier to execute async fetch and fetchRelated requests. Further there was is a bug in Backbone-Relational that didn't respect the silent option passed automatically by backbone when saving an object with wait: true. See the https://github.com/PaulUithol/Backbone-relational/pull/153 for the pull request to fix this.

hop of those help? The page you're referencing is incorrect, nothing in Backbone inherits from Backbone.Events. However, Backbone.Events is mixed into the other Backbone "classes". The bit of code you mention:
code :
_.extend(Model.prototype, Events, { ...
for k in Events
    Model.prototype[k] = Events[k]

may help you . Is your question, how do you call the original sync method? If so, you're almost right. You just have to change one line:
code :
orig.apply(Backbone, arguments);

like below fixes the issue If you want to change your persistence methods, you should override Backbone.sync
Backbone.sync
code :
Backbone.ajax = function() {
  return Backbone.$.ajax.apply(Backbone.$, arguments);
}

will help you AFAIK, you cannot use stopPropagation in this context.
One quick and (very) dirty solution could be setting a (global) variable in the drawend callback (eg. skipCoordinatesPopup) and checking it inside the singleclick callback.
code :
map.on('singleclick', function(evt) {
  if(skipCoordinatesPopup) {
    console.log('skip popup while drawing marker');
    return;
  }
  var coordinate = evt.coordinate;
  var hdms = ol.coordinate.toStringHDMS(ol.proj.transform(
          coordinate, 'EPSG:3857', 'EPSG:4326'));

  content.innerHTML = '<p>You clicked here:</p><code>' + hdms + '</code>';
  overlay.setPosition(coordinate);
});
map.addInteraction(mark);
skipCoordinatesPopup = true;
