Dont redraw the whole tree when checkbox was checked/unchecked

This was causing delays and was resulting in saving incorrect data when checking/unchecking lots of nodes in the tree very fast.  We dont need to redraw the whole tree to change the text color of checked/unchecked nodes and it's children in the tree to show user the changes in the tree. Fixed to only render the node that was checked/unchecked and it's children to show differences in blue color.
