* Updating defcustom variables in elisp code

Have used defcustom as follows

(defcustom px-frame-initpos (cons 8 8)
  "Position of initial frame."
  :type 'sexp
  :group 'px-frame)

Then inside some function, I want to reset the value of "px-frame-initpos".
Have been using 

(custom-declare-variable 'px-frame-initpos (cons lft top) "DESC")

Perhaps using "custom-declare-variable" is not the appropriate thing to do, as it seems 
that it is declaring the variable from scratch, needing also ":type" and ":group".

Do this:

{M-x customize-group RET savehist RET}

Find:

Hide Savehist Additional Variables:
Repeat:
[INS] [DEL] Variable: rcd-sample
[INS]
   [ State ]: SET for current session only.
   List of additional variables to save. Hide
   Each element is a variable that will be persisted across Emacs
   sessions that use Savehist.
   
   An element may be variable name (a symbol) or a cons cell of the form
   (VAR . MAX-SIZE), which means to truncate VAR’s value to at most
   MAX-SIZE elements (if the value is a list) before saving the value.

As that can save variables.

I did that, but although the new values get updated, the defcustom in the file  
used during init resets to the default values.

In my file I define

(defgroup tpframe nil
  "Set position of frame."
  :group 'convenience)

(defcustom frame-pos (cons 8 8)
  "Position of initial frame as (X . Y) ."
  :type 'sexp
  :group 'tpframe)
