email_field id doesn't propagate to label

[typeoneerror]

If you use a custom id with email_field the label's "for" is still the default:

= bootstrap_form_for :purchase do |f|
  = f.email_field :email, id: "my_custom_id"

result:

<div class="form-group">
  <label class="control-label" for="purchase_email">Email</label>
  <input id="my_custom_id" class="form-control" type="email" name="purchase[email]">
</div>

expected:

<div class="form-group">
  <label class="control-label" for="my_custom_id">Email</label>
  <input id="my_custom_id" class="form-control" type="email" name="purchase[email]">
</div>
