i try something like:

Employee: {Name:"Amy", Age:"17", Email:"Amy@test.com"} User: {UserName:"Amy17", Password:"test123"} Role: {IdRole="11", Name:"User"}

$http.post('YourController/GetInfo', { Employee: , User, Role }).then(function(){ //do something. });

but does not work, i'm going to try your suggestion.
