Hi i got the following app

after i click green button and select one record of grid i generate a html table like the top one (field name P8_HTML_TABLA)

i got the value saved as placeholders for email template
then i got the dynamic action to send email

but when i click on green button nothing happens

this is my button config, if i use Submit after click as action then email is sent but without the html table data traveling as i have it in my email template:

what im doing wrong? any tip
thank you
