It works for me.
Debug onMouseDown function in Ext.grid.CheckColumn.prototype through firebug.
Make necessary changes in it.

thanks tomceng76
but i think its me who get error,
i use same index to 2 checkColumn

to add more than one grid, you just set them like an array, like
...
plugins: [check1, check2, another plugins]
...

thanks for all, and sorry
