initialize dataTable does not work

Hello,

I am using jquery dataTable version 1.9.4.
But, init dataTable does not work.
All properties don't work.
Example:

$(document).ready( function () {
  $('#example').dataTable( {
    "bAutoWidth": false
  } );
} );

When I set any property (bAutoWidth, bLengthChange, bPaginate...), no change happens to the table.

Please, if someone has an idea, I will be grateful.

Best regards,

Omri
