Clicking on buttons

When I click on the +/- in front of my nodes in my tree,  the children appear/disappear like they are supposed to.  The problem is that they also appear/disappear when I click anywhere inside the range of the DIV tag that encloses the +/-.  Is there a way to specify an onclick for only the area immediately around these buttons.

Thanks in advance,
