ajax fail

When data/request is ok, resolve(data) renders the table, but when there is a problem with request what should reject() do? I'm using $.Deferred and returning the error string from the error method does nothing. Can we stop fetching and handle error message?

$.ajax(...).then(function(data){return data.mydata}, function(err){return err.text})
