Creating custom callback functions

Is it possible to create a custom call back function that can be called when a block has changed? I'd like to check if the user changed a property in a block and if they have I'd like to update the blocks display to reflect the change. The current callbacks won't allow for me to set something up when a block has changed. I didn't know if there was a way to determine something like this or not. Thanks.

For which block you want this ?

For any simulink's inbuilt block or for your own masked subsystem block ?

If I understand correctly, you're looking for a callback to run when a dialog parameter is changed? You can do that by creating a mask for your block, and using the mask parameter callback.
