Coffeescript/Javascript loop not executing

I have a simple coffeescript to process a specific selector (part_ids) ..

 alert "Starting  blines  " + $("[id*=part_id]").length
 for bl in $("[id*=part_id]")
   do(bl) ->
     procBl bl

  procBl  = (bl)  ->
     alert "# of children "  + bl.children().length

First alert show 2 items are on the page. For loop runs -- however the procBl doesn't print the alert (it quietly exits) It appears that bl that's being iterated and passed to the function is not the correct object and I can't figure out what's it and wrong with this code -

any help is appreciated

bl passed into procBl function is not a jQuery instance, but plain DOM element. Wrap it with $() to use children method:

  procBl  = (bl)  ->
     alert "# of children "  + $(bl).children().length

... or use $.fn.each method to iterate over $("[id*=part_id]") collection.
