Use of Ajax-chosen with webservice

[ghost]

Hi,

i am trying to implment ajax-chosen in my webpage using a webservice so that i can populate the select control with values when the user types in the search box. the dropdown should be loaded on the page load and then the user can filter out the options. Please find my code below:-

the webservice is not getting called am i missing something ? i need to pass whatever is typed in the search box and pass it to the webservice.

i am using Chosen 1.0.0 and ajax-chosen pulgin is also installed.

Regards, Vineet
