invoke CallBack, update the new form data.
Arguments:
Selection - The current selection of the form.
CallbackData - The pointer to host the data passed back by the callback function.
FileFormTagsHead - Prompt string token of the one-of box
IdValue - The current page number.
FormHandle - Output the the handle of the form.
TitleToken - Output the TitleToken of the new page.
FormTags - Output the FormFags of the new page.
