How to change the rails-bootstrap-forms tab in Rails 4

Question

I have been playing with Rails for about a year now, and I'm working on my first application, which is actually going into production. Since this is a more utilitarian application, and it should not be very bright, I decided to use Bootstrap CSS libraries to speed up the user interface design.

I am using rails-bootstrap-forms gem and I have text fields in different divs for layout. I would like to change tabindexfor the fields to the field first_nameand last_namewere next to each other in the tabbing order. Is there a way to pass this parameter to the form generator?

Here is an HTML form snippet:

<div class="row">
  <div class="col-sm-5">
    <%= f.text_field :first_name, label_col: "col-xs-6", control_col: "col-xs-6" %>
    <%= f.text_field :teacher, label_col: "col-xs-6", control_col: "col-xs-6" %>              
  </div>
  <div class="col-sm-5">
    <%= f.text_field :last_name, label_col: "col-xs-6", control_col: "col-xs-6" %> 
    <%= f.text_field :room, label_col: "col-xs-6", control_col: "col-xs-6" %>
  </div>
</div>
