autocomplete type search error

Hi,
I m using jquery 1.10.4 js & 1.10.4 ui on my page  for autocomplete feature. after writing the code i got the error
" Uncaught TypeError: Cannot set property '_renderItem' of undefined ".
I searched this error on google and found solution but these solution are not working. Pl tell me how to resolved this error.

i used 
.data('ui-autocomplete')._renderItem 
.data('ui-autocomplete-item')._renderItem 
.data('uiAutocomplete')._renderItem 
but all three are not working.
