partial templates question

hi, i have a question about partial templates.

there is a table - Topics, it has one field - Title.

there is a text_field form with button, and a partial template under
the form. they are in

the same template. the partial can display Titles which is already in
the Topics table.

user enter a string in the form, click the button. the string will
save as Title in Topics

table. the partial will display all the data from the Topics table,
including the string

which user just entered.

i have been thinking all day, but can't find a solution. can someone
help, give me a

solution. thanks very much!
