        <li>
            <input type="submit" value="save" class="button1"/>
        </li>
    </ul>
</div>

notice that the sign close is used three time here , it works for the first time at the div aqSugQues , but doesn’t work at the div aqSugInfo nor the div aqSugHints

the ajax is working good and i print the results

thanks for helping

Answer 1

This line:

$("#aqSugInfo").html('<div class="closeSign1"></div>');

is replacing the contents of the div with a new button that doesn’t have the click-event bound, so every time you update, that button will lose its binding.

You might try wrapping your dynamic content in a container that you can easily remove, or do something like

$("#aqSugInfo").children(':not(.closeSign1)').remove();
