Using $._data, yea!

Yes, you can do so by checking this way:

console.log($._data( $(element)[0], "events" ));

Example

​$("#foo").on({
    click: function(){ alert("Hello") },
    mouseout: function(){ alert("World") }
});​​​
​$._data( $("#foo")[0], "events" );

Output

In your code:

So, you can use the returning object and perform operations.

myEvents = ​$._data( $("#foo")[0], "events" );
// Check if the mouse event is set
if (myEvents.mouseout.length > 1)
    // Do something
