passing data from mashup to service

Hi, hoping you're doing well

I don't finish to fully understand how work properly with thingworxs so I ask for your help again

I have a test Mashup

when I click the butto marked in red I got the results form db, this works fine

Now I need to get the datetime when I clicked the button222 (marked in blue) and pass this datetime to a service

I also made a generic service that gets an input parameter and log the data

I tested the generic service alone and works

But I cannot bind what I need from the mashup to the service or I dont know how to do it,...

How can I bind the click event to get the datetime from the datetime widget and execute the service with this value as an input parameter?

Please, do you have the proper coding to do that? so I can tested

Best Regards,

Marcos
