Apply Bootstrap Tokenfield on a Class instead of Id

Question

I have some dynamically generated form input fields where I want to apply Bootstrap tokenfield.

It is possible to apply tokeninput on a class using the following code. Tokeninput is applied on all input fields with class 'someclass'. 'someurl' fetches the remote JSON data.

    $(document).on('focusin', '.someclass', function()
    {
      $(this).tokenInput('someurl');
    });

I would like to achieve similar functionality using tokenfield. Kindly help.
