Looks like a similar question as in get the value of a select box

Yes, but the problem is that it doesn't show me the value when 
the user changes to another option, for example, he selects the x 
value of a text box but it doesn't show it, it only shows 
the default value.
I need it to show me the value that I select in real time

#binder.options.FORM_DEF_ID.FIELD_ID#

The Joget hash variable only works for data values ALREADY saved into the database (and not changes in client side browser form that's not saved yet).
FYI the Joget form hash variable is a shorthand database query; "#form.table.email[{requestParam}]#" instructs Joget to:

select c_email from app_fd_table where id=#requestParam#
