How to add options to select_box helper, if {{select_box "payment_mode" optionValues='Cheque Cash'}} it will generate following html:-

<select class="form-control" name="payment_mode">
  <option value="C">C</option>
  <option value="h">H</option>
  <option value="e">E</option> 
  <option value="q">Q</option>
  <option value="u">U</option>
  <option value="e">E</option>
  <option value=" "></option>
  <option value="C">C</option>
  <option value="a">A</option>
  <option value="s">S</option>
  <option value="h">H</option>
</select>

when optionValues passed like an array {{select_box 'payment_mode' optionValues=['Cheque Cash'] }}, it raises an Exception
