Maybe it is not a form onupdate action that I need.
I guess that to dinamically update field "b" in the form I need to attach a
JQUERY action to the custom field "a" , but I don't know how to do it.
For instance I would like that during updating, when the user writes 5 in
the field "a', field "b" becomes 5+2
index.html
{{extend 'layout.html'}}
{{if grid.update_form:}}
{{=grid.update_form.custom.begin}}
{{=grid.update_form.custom.widget.a}} ## WHEN a CHANGES I WOULD LIKE TO
MAKE b CHANGE
{{=grid.update_form.custom.widget.b}}
{{=grid.update_form.custom.submit}}
{{=grid.update_form.custom.end}}
{{else:}}
{{=grid}}
{{pass}}
