Website not scrolling in mobile devices with skrollr

Question

I am using twitter bootstrap for my website . I am also using skrollr.js for parallax effect in background.But website becomes fixed to top while viewing in the mobile devices.but According to the skrollr documentation i am also using #skrollr-body in my document But it does not scroll in mobile devices.I have seen some questions from stackoverflow and seen the answers and tried as follows :

#skrollr-body{
  position : relative;
  width : 100%;
  height : 100%;
}

How can i fix the scrolling problem?
