strange behavior with materializecss and jade

[palpinter]

Hi

i dont understand why, but:

this works:

      div.help-item
        ul.collapsible(data-collapsible="accordion")
          each item
            li
              div.collapsible-header
                span {{{title}}}
              div.collapsible-body
                span {{{body}}}

this doesnt:

      div.help-item
        each item
          ul.collapsible(data-collapsible="accordion")
            li
              div.collapsible-header
                span {{{title}}}
              div.collapsible-body
                span {{{body}}}

I see the difference script initialization within 'each' helper. but i dont know whats the real difference.

any idea
thx
