Bind property to another input name in nested array property

The data in JSON format is sent to api endpoint.

Data sample:

    {
      "templateId": "dc15e4d1-ccbd-4581-a819-5b7f90b32cc5",
      "name": "abc",
      "steps": [
        {
          "id": "34b4f406-120e-4d80-8018-6c780c80a6c4",
          "visible": false,          
        }
      ]
    }

Api gets data in this format:

public class TemplateRequest {
        public Guid TemplateId { get; set; }

        public string Name { get; set; }

        public StepRequest[] Steps { get; set; }
}

StepRequest class:

public class StepRequest {
        [ModelBinder(Name = "id")]
        public Guid StepId { get; set; }

        public bool? Visible { get; set; }
    }

The JSON has id key instead of stepId, but I can't get it in controller.

When I check, the StepId is always an empty Guid.

What is wrong here, why the StepId property is not having the value from id key?

Yes, like @daremachine said, it was NewtonSoft and JsonProperty(PropertyName = "id") helped.
