@hango before the call to hideModule
there is a variable self set
self is used to avoid the ambiguity of ‘this’, as inside callbacks ‘this’ can point to the caller, NOT the context where it was intended.

	var self = this;     < ----- self is initialized to the current 'this' context
	MM.hideModule(
		self,              < -------------- should be 'this' ?
		speed,

so its the same
and in the call there is a required function (the callback), in this case created inline

		function () {
			self.suspend();   // < --- make sure to use the right module context when this function is called
                                                  // the compiler remembers that self was defined above 
			callback();         // call the routine defined as callback
		},
