This happens because the formatters are applied first before validators.
The formatter in the case of 'number'

var minValidator = function(value) {
var min = parseFloat(attr.min);
return validate(ctrl, 'min', ctrl.$isEmpty(value) || value >= min, value);

If you remove ng-model attribute, you see the initial value.
If this is NOT a bug, when we type invalid value such as 40, we must not see the entered text as it happend as when initialized. See, it's not consistent.
It only happens for the first time when input directive is initialized.
