How to detect valid prop/session type?

[pgilad]

Suppose I want to set the value for a model prop or session. How do I detect what is the valid dataType for that attribute?

This is useful when getting e.target.value from inputs, and when type='number' it will fail validation due to the required type being a number. Thus what you should use is e.target.valueAsNumber but you have no way of knowing ahead what is the required data type.

So either model.set should handle the type coercion, or you should be able to somehow determine programmatically the required type and coerce it yourself (something like model.getPropType('amount') --> 'number')
