[jQuery] I would like to get value each time when one of these checkboxes will change status, how can I do that ?

[dziobacz]

I have:

<input type="checkbox" checked="checked" value="2" name="number"/>
<input type="checkbox" value="7" name="number"/>
<input type="checkbox" value="34" name="number"/>

I would like to get value each time when one of these checkboxes will
change status, how can I do that ? For example when first checkbox
will be unchecked or second will be checked. Could You help me ?
