title: How to send parameters to the JavaScript method that aren't constants?
body: <p>As shown in the image below, I can provide my little method with a lot of stuff. The thing is that I want to send in e.g. first name of the contact I'm currently on. The field doesn't seem to be able to read the contents of the boxes on the same form that the calling control is on.</p>
  
  <p>The approach now is to execute the method without parameters and let it fetch it's own data as it pleases. However, I'd like it better if I could provide it with some junk. How can I send in dynamical parameters into it?</p>
  
  <p>Should I go for dependencies? I've always thought of them as "stuff the method will see if you query for them" and not "parameters that will be sent in"...</p>
