Html elemet + Ajax

I have a page with a TEXTBOX and a BUTTON within a form.
When the BUTTON is pressed system (using Ajax) reads and loads some html elements (CHECKBOX and SUBMIT BUTTON) in that page.

The SUBMIT BUTTON which is loaded from second page works with internet explorer but does not work with Firefox and Chrome.

Please advice to make SUBMIT BUTTON work with all browsers.

Please post the html and js/ajax code so we can take a look at it.
