Rails4: How to pass dynamic array from view to controller - ruby-on-rails

Question

I have a problem creating Vote which contains value of points that user decided to give for a candidate (Borda Count Method). Values are in number_fields and I want them to be saved in Vote objects.
In my case I am only able to get value from the last number_field and I have no idea how to fix it. Other values are being overwritten so I came up with idea to create an array of points which contains values taken from many number_field_tag and pass them from view to controller.
Something about survey structure:
There is a Surv (survey) which contains many Polls (questions).
One Poll contains many Vote Options.
There are also Votes which save votes of user.
OUTPUT from params
{"utf8"=>"✓", "poll"=>{"id"=>"11"}, "9"=>"17", "arr"=>"1212", "pnts"=>"", "10"=>"20", "11"=>"22", "commit"=>"Zagłosuj", "controller"=>"votes", "action"=>"create"}
VIEW:
show.html.erb
<p id="notice"><%= notice %></p>
<h2>Twoja ankieta:</h2>
