Comment:

 @nfmohit This is more of a support question which you'll need to post on
 wordpress.org/support, but the problem seems to be that a) you're using
 `add_action` instead of `add_filter`, and b) you're missing a return
 statement in your callback(s). This  combined causes the default arguments
 to be passed to `wp_dropdown_pages()` which causes it to be unexpectedly
 output instead of assigned to a variable and used later.
