the web service.asmx methods not being fired @ when inspect network request through firebug .the url not being resolved correctly.try putting full path website service path this

servicepath="http://smirdex.gr/orderform2.2/webservice.asmx" 

or resolve url

servicepath="<%# resolveurl('~/orderform2.2/webservices.asmx') %>" 

let me know how goes
