Ajax & WordPress on Front End - Database not updating

Question

So I\'m working on a WordPress website. I\'m having a bit of a difficult time getting the user input to update the database.

JS:

var ID = $(this).at

$wpdb->update( 'table',
array( 'column' => $name),
array( 'ID' => 1 ),
array( '%s'), 
array( '%d' )
);
