i have a WHDG with a templated delete button in the child band. clicking the button doesnt fire the javascript, thus the row doesnt delete and thus the code behind doesnt delete the row from the database. BUT if i press the delete key on the keyboard the row deletes as it should. below is the grid and the javascript
