how can i update first then send the email with one button?

for example, in the model dialog, when i changed the date and click the send email button. first, i need to update the informations then run the send email process,

to be clear, i want to give you demo what i want to achieve,

first i open the model dialog and then change some names or dates after i want to click the send email button, send email button should update the informations first and then run the process (send email process).

i tried a few dynamic actions, i made two process, first one row processing with condition when button sendmail and second one send email process when button send email.

this is my screen

To me, it looks as if

• SEND EMAIL button should submit page (which will also save changes you've made)
  • set "Database action" property to "SQL UPDATE action"
• create a process which sends mail and runs when SEND EMAIL button is pressed
