elm_naviframe_item_pop_cb_set(nf_it,naviframe_pop_cb,nf); 

static Eina_Bool naviframe_pop_cb(void *data, Elm_Object_Item *it) {
 /* By returning FALSE, you can reject the popping the item */

if(press 2 times quickly)
   return EINA_TRUE;

else

  return  EINA_FALSE;
}

Create a global variable. Increment  that variable value in pop callback function (Eina_Bool naviframe_pop_cb). Return true when global variable value is 2 
within a specific time.

int cnt = 0;

static Eina_Bool naviframe_pop_cb(void *data, Elm_Object_Item *it) 
{
 /* By returning FALSE, you can reject the popping the item */
 
cnt++;

if(cnt==2)
   return EINA_TRUE;
else
  return  EINA_FALSE;

}
