Label for checkbox is not displaying in ESP form

The label for checkbox is needed to marked with <label for='id'>. The following code:

  <input type='checkbox' id=...>Label Text</input>

was working for Chrome/Firefox, but not any more. It is not HTML compliant anyway. The right usage is:

<input type='checkbox' id='id1' .../> <label for='id1'>Label Text</label>
