start_new_page uses the same grid layout as first page - override is not working

[sthennarasan]

Basically, I am trying to create a pdf with different contents on first page and different content on page 2, but start_new_page always gives the grid system that was created for first page.

    def initialize()
      document_setup
    end

    def render
      show_grid
      header_left
      header_right
      content
      footer
      start_new_page
      show_grid
      page2_setup
      page2_header_left
      page2_header_right
      page2_content
      page2_footer
      self
    end

    def document_setup
      define_grid(columns: 4, rows: 32, gutter: 8)
      @grid_header_left = grid([0, 0], [10, 1])
      @grid_header_right = grid([0, 2], [10, 3])
      @grid_content = grid([11, 0], [28, 3])
      @grid_footer = grid([29, 0], [31, 3])
      document.font 'Helvetica', size: 10, line_height: 16
      document.default_leading 5
    end

    def page2_setup
      define_grid(columns: 4, rows: 32, gutter: 8)
      @p2_grid_header_left = grid([0, 0], [5, 1])
      @p2_grid_header_right = grid([0, 2], [5, 3])
      @p2_grid_content = grid([6, 0], [20, 3])
      @p2_grid_footer = grid([21, 0], [31, 3])
      document.font 'Helvetica', size: 10, line_height: 16
      document.default_leading 5
    end

Why is page2_setup not overriding the first page grid layout?
