NativeCheckboxItem VS CheckboxItem

Hello,

I'm using SmartClient_v91p_2014-05-04_PowerEdition and I need to implement a checkbox item that have title to the left in a separated cell and have click callback. If I use NativeCheckboxItem the click function works but the title is in the same place as the checkbox. If I use CheckboxItem the title appear to the left in a separated cell but the click function callback doesn't work. What to do?

Thanks.
