Shipment plugin

[JibutuFlavour]

I want to write a shipment plugin where the user can select a PickUp place from a select box.
My idea (maybe wrong) to make an ajax call on select to my plugin and trigger

Code Select Expand

public function plgVmOnSelectCheckShipment(VirtueMartCart &$cart)

But i have no idea how to call a plugin's (own) method via ajax.

Can someone help?
