Jdate and Ajax

[teoyh]

I have a start and end date which when the user change will trigger a Calc Duration field which i trigger a calculation of the 2 dates to get the duration in Months
But some how the jdate element is not triggering the calculation but when i change to a date field it works
Anybody have this similar issue can advice what i did wrong , thank you in advance
