onkeypress event

Hello people! I have a scritp to allow only numbers in a phone field.
If I use this script directcly in a <input> field, it works fine, but an error appears when I use it the [tel] structure.

This is the code:

<!-- header -->
<script language=javascript>
  function isNumberKey(evt)
  {
	 var charCode = (evt.which) ? evt.which : event.keyCode
	 if (charCode > 31 && (charCode < 48 || charCode > 57))
		return false;

	 return true;
  }
</script>

It works fine here but CF7 doesn’t validate the tel field:

<!-- input field -->
<input id="nunChar" onkeypress="return isNumberKey(event)" type="tel" name="my_phone" minlength="11" maxlength="11" placeholder="00112223334">

It doesn’t work here:

<!-- CF7 tel field -->
[tel* pk_numero_cuit id:nunChar onkeypress:"return isNumberKey(event)" minlength:11 maxlength:11 placeholder "00112223334"]

The question is where exactly should the code [ onkeypress=”return isNumberKey(event)” ] be placed ??

Thanks in advance for your kind help.
