TypeError: 'undefined' is not a constructor

[Instrumentry]

I'm getting the above error in console that fires at the rate of mousemove.

Here's what my code looks like:

$('#element').bind('mousemove', {
    behavior: 'throttle',
    delay: 200
}, someFunction);
$('#element').bind('mousestop', 1000, anotherFunction);

The intended behavior works though.
