Possible to run API call on demand?

I love the AppGyver interface but i was having lots of trouble getting details from an API call.

Can AppGyver do an API “call on demand”?
A user would enter parameters, then click a button.
That would trigger an API call and the app would display the results.

When my app boots, it’s fine, the API call goes thru, gets the info based on default params.
But when I try to implement a customized call, it makes the second call - according to the debugger
but the variables to receive the new info do not refresh.

Any help appreciated!

Do you use the set data variable or even a logic to set the new data?
some images of the request logic would help
