dmon | Single header C99 portable library for monitoring directory | Runtime Evironment library

Ok so I have a bit of a double barrelled issue here.

What I'm doing is I have three select boxs that a user can pick a date for.

The year is predefined as is the Months. When a user selects a month (or year) the day drop down figures out how many days are in that month for that year and populates them appropriately.

The firs issue is with using the normal .change()event found in the first section of code. What happens here is what I would expect to be fair. it populates the front end properly but when you select a box the dom forces a value of 1.

To combat this I used the on change event delegation which you can find in the second section. Which works fine in the sense that when you pick a value you get that value. But for some reason when using event delegation the function to find the correct day range for the drop down doesn't work.

I was hoping to get a second pair of eyes on it just to see where I'm going wrong.
