Using a function from an Action in a Scriptable task

Hello,

I am new to vCO and Java Script and I was wondering if I could call an action in a scriptable task.  Basically I am creating a workflow that is integrating with vCAC and I want to pull the properties from the Virtual Machine and change the varible names to invoke a soap request for another service.  I see that in the plugin there is getPropertieFromVirutalMachine can I call that action in my scriptable task to do an update in my scritpable task to reset the varibles? Essintally I want to know if I could do something like this:

(I know that this doesnt work)

var properties = new Properties();

properties.put("VirtualMachineID", virtualMachine.virtualMachineID);

var vmProperties = {

            applicationResolver = getPropertyFromVirtualMacine(host, virtualMachine, "property");

};

System.log(applicationResolver)

or do I have to do it another way by going through the vCAC entities
