Backbone.js

I finished the UI for taking an exam. The Backbone code looks like this

  questions = new Altair.Collections.QuestionsCollection
  assignments = new Altair.Collections.AssignmentsCollection
  questions.reset(#{@assignment.questions.to_json})
  assignments.reset(#{@assignment.to_json})
  assignment = assignments.get(1)
  answer = new Altair.Collections.AnswersCollection

  $(function() {
  render_question()

  function bind_click(){
  $('.anslink').click( function() {
    ans = $(this).text()
    question = $(this).parent().find(".question_id").val()
    answer.create({'question_id' : question, 'answer' : ans})
   })
   }

  function bind_submit(){
  $('.nextquestion').click( function() {
    assignment.fetch()
    assignment.set({'current_id' : current + 1 })
    assignment.save()
    render_question()
   })
   }

   function render_question(){
    assignment.fetch()
    current = assignment.get('current_id')
    q = questions.get(current)
    r = new Altair.Views.Questions.ShowView({'model': q})
    r.render()
    $('#question').html(r.$el.html())
    rightWrong()
    bind_click()
    bind_submit()
   }
}
