I declared a BigIntegerField in a model, but the field actually created by mongodb is an Int32. I want Int64, but it doesn't work. My djongo version is 1.3.6. I want to know if it is a bug or my mistake.
Python script
```python
from djongo import models as djongoModels
class TestModel(models.Model):
...
reservationNumber = djongoModels.BigIntegerField(default=0)
...
```
#### Traceback
One line description of the issue
