Do you have it set up as an Exchange account? I once had a similiar issue and solved it by using microsoft exchange account setup for Gmail contacts and calendars (google how to do this, google has it in a blog somewhere) and now both my calendars and contacts sync both ways.
The birthdays that show up in Calendar are a special calendar displayed on the iPad using the information in your Contacts. Syncing the calendar doesn't do anything to move these to Google.
By setting up your Google account as an Exchange account you can sync your Contacts which would make those dates available to Google, but I have not found a way for Google Calendar to automatically detect and display the birthdays in your Google Contacts. Not that my failure to find the feature means that it isn't there. Could be.

i appreciate your help very much...thank you!
but i should clarify, it's not birthdays reading from my contacts.
Any and all manual entries into my ipad are not uploading to my google calendar.
I want to be able to enter appointments and such in my ipad and have them go to my google account. I just happened to say birthdays because I manually entered them when I first got my ipad. Hope that clears things up.
i think you need to delete your gmail from the iPad and start over, this should not be an issue.
and earlier i was checking this with my ipad1 and could not see edit, but my iPad 2 i see edit.
edit: on ipad1, i turned off calendar, and turn it back on, and is able to see edit.
this way should guarantee a fix.
The exchange account won't merge previous entries on your iPad calendar automatically, you either, as poser suggests delete them all and re enter them or you can actually edit them on the iPad and just change the calendar they are stored to. I appreciate it may take a long time for a lot of entries but I've no easier way at the moment.
Okay, I get it now. I'm going to have to edit all the old entries to get them to appear.
New entries have to be listed on my gmail cal on the ipad. Wow...bummer! I truly thank you for your help! Have a fabulous day!
