I have found the combobox onChangeCommitted event to give better response.
onChange fires even when you use the arrow key to navigate (even though
You have not committed the change). So it may be a case of multiple
firing of the same event.

Try using the onChangeCommitted event.
In the constructor code of your combobox there will be a line similar to

       onChange = class::CBFIND_onChange

in the code editor change it to

onChangeCommitted = class::CBFIND_onChange

Give it a try. If it succeeds then okay otherwise you  can easily revert
