smartGwt listGrid checkBox not real selection

Hi , I am using smartGWT 4.0

I have a listGrid with RecordClickHandler and each record contains a checkBox,

when I want to select the checkBox the RecordClickHandler is invoked , but this is not the behavior that I want,

I want to select the check box to have a different behavior than the
recordClickHandler,

ie. as the attached I am using the listGrid as a left menu to control a multi views page , so when I select a checkBox a new view is loaded and I don't want that to happened, I want the selection to do nothing .

The selection on check box should has different behavior that clicking the row record.
