Datatable filter function doesn't working properly.

Hello,

I made one filter page like flipkart etc.. and given two filter option using select box 1) Less than (<=) 2 Greater Than (>=)

On change of select box, i called data table ajax..

it's working fine with greater than even data table search functionality.. but when i am using <= sign then i got the listing properly but when i m trying to search in this list then doesn't getting any data.. but the data is already there.

can you guys let me know what is the issue ?

Thanks
