jquery - Bootstrap drop down stops working after appending child elements to it -


i using bootstrap 3.2.0 , jquery 1.7.1 , using 2 bootstrap drop downs on web page.

the user selects value in first drop down , jquery runs , fills respective values , prices in second drop down.

the onchange event works fine on first drop down onchange event stops working on second drop down after populated via jquery (based on selection of first drop down).

i @ loss why happening.

i have coded example here

http://www.offshoreprojectupdates.com/testb/test_page.php

can 1 pinpoint may doing wrong in above code?

update

i have removed code solution have found requires there no adding/deleting of elements on drop down. have tried solutions available on internet no avail. if 1 have solution please share it.

bootstrap adds click/change handlers various elements.

if notice element's onchange events no longer firing, it's because modifying dom (adding, inserting, removing elements) inadvertently breaking bootstrap's event handlers.

you must either find way achieves same thing not destroy existing handlers.

or have tell bootstrap rebind event handlers after you've done dom manipulation.

i.e. calling $('.dropdown-toggle').dropdown() when appropriate.
