Sravanthi,
What version of Agentry client are you using for iPad? What field types are you using on your screen for the CT? CT Dropdown or CT Search? I would recommend CT Search on smart devices (iPad) and CT Dropdown on Windows (With the 'always open with search' option used on the CT settings tab). Trying to use the CT Dropdown with search option on tablets is very buggy depending on your version.
