please help me resolve issue.. in advance

your loop problem.

for (i=0;i<paginationcount;i++) {

if there no 20 items in data.data array fail, instead safe thing is

for (var i=0, len = data.data.length;i<len;i++) {

you using static count paginationcount loop counter value, if returned result not have paginationcount number of items loop seek access elements out of bound resulting in returning undefined
