Event bubbling/capturing/delegation in ember - events

Question

It is hard to expliain the actual code as i dont exactly know where the problem is, but it will be great if anyone can help in explaining how events are delegatd/bubbled in Ember.
I have a case where mouse move on document is not triggered inside one view. This happens when the view gets inserted dynamically using outlets.
MOUSE MOVE BINDING CODE:
MOVE_EVENT = touch ? 'touchmove' : 'mousemove',
$(document).on(MOVE_EVENT, function (e) {
console.log('move event move=true');
if (move) {
e.preventDefault();
stop = getY(e);
//console.log('move event move=true');
var val = pos + (start - stop) / h;
val = val > (max + 1) ? (max + 1) : val;
val = val < (min - 1) ? (min - 1) : val;
inst.scroll(target, val);
}
});
If I load the page with a router URL that shows the view in the outlet by default, the mouse move inside the view triggers mousemove on body. And when I gets into the view by changing states it doesnt happen: here is a log of a statechage that leads to the behaviour.
mouse move in repeat view
move event move=true
mouse move in repeat view
move event move=true
STATEMANAGER: Sending event 'chooseSkipTime' to state root.ote.
STATEMANAGER: Entering null
STATEMANAGER: Entering root
STATEMANAGER: Entering root.ote
STATEMANAGER: Entering root.ote.repeat
STATEMANAGER: Entering root.ote.repeat.skiptimes
STATEMANAGER: Entering root.ote.repeat.skiptimes.index
skiptimes view Inserted
skiptimes is inserted into an oulet on RepeatView. After such a state change the mouse move inside repeat view is not getting triggered, or it is not triggering the mousemove on document. At this same time as I move mouse outside the area of the parentview(RepatView) then mouse move shows log.
In a nutshell mousemove inside a view is not triggered. I have put:
mouseMove : function(e){
console.log('Mouse Move in Blah Blah View');
}
in every view inside RepeatView including RepeatView, none triggers. But mouse move on Parent of RepeatView and upwards is triggering as logs are shown.
It is hard to expliain the actual code as i dont exactly know where the problem is, but it will be great if anyone can help in explaining how events are delegatd/bubbled in Ember.
UPDATE
After further investigation it looks like the following stopPropogation in ember-latest is causing this, not yet able to understand why its going to else.
setupHandler: function(rootElement, event, eventName) {
var self = this;
rootElement.delegate('.ember-view', event + '.ember', function(evt, triggeringManager) {
var view = Ember.View.views[this.id],
result = true, manager = null;
manager = self._findNearestEventManager(view,eventName);
if (manager && manager !== triggeringManager) {
result = self._dispatchEvent(manager, evt, eventName, view);
} else if (view) {
result = self._bubbleEvent(view,evt,eventName);
} else {
//evt.stopPropagation();
}
return result;
});
