I can not insert, delete or update data Web API Service.

Hello! I use in the project Dotnet Core 2.1.4 WebApi and Angular 6. I use devextreme-aspnet-data-nojquery. When loadUrl data is sent to the client, and when using insertUrl, updateUrl, deleteUrl, the data is not received by the server.

Client:

import { Component, ChangeDetectionStrategy } from '@angular/core';
import { Api } from 'src/app/lib/_servers';
import CustomStore from 'devextreme/data/custom_store';
import { createStore } from 'devextreme-aspnet-data-nojquery';

@Component({
  selector: 'app-building',
  templateUrl: './building.component.html',
  styleUrls: ['./building.component.css'],
  changeDetection: ChangeDetectionStrategy.OnPush
})
export class BuildingComponent  {
  masterDetailDataSource: any;
  dataSource: CustomStore;

  constructor() {

    this.dataSource = createStore({
      key: 'id',
      loadUrl: Api.uavr + '/JBuilding/load',
      insertUrl: Api.uavr + '/JBuilding/InsertJBuilding',
      updateUrl: Api.uavr + '/JBuilding/UpdateJBuilding',
      deleteUrl: Api.uavr + '/JBuilding/DeleteSection',

      onBeforeSend: function(method, ajaxOptions) {
        const jwt = JSON.parse(localStorage.getItem('currentUser'));
        ajaxOptions.xhrFields = { withCredentials: true };
        ajaxOptions.headers = { 'Authorization': 'Bearer ' + jwt.token };

        console.log(ajaxOptions);
      }
    });
  }
}

Server

    [HttpPut("UpdateJBuilding")]

    public IActionResult UpdateJBuilding(int key, string values)
    {
        var section = _uavr.Jbuilding.FirstOrDefault(o => o.Id == key);
        if (section == null)
            return StatusCode(409, "Ошибка, раздел не найден");
        JsonConvert.PopulateObject(values, section);

        if (!TryValidateModel(section))
            return BadRequest(ModelState.ToFullErrorString());

        _uavr.SaveChanges();

        return Ok();
    }


    [HttpPost("InsertJBuilding")]

    public IActionResult InsertJBuilding(string values)
    {
        var newJBuilding = new Jbuilding();

        JsonConvert.PopulateObject(values, newJBuilding);

        if (!TryValidateModel(newJBuilding))
            return BadRequest(ModelState.ToFullErrorString());

        _uavr.Jbuilding.Add(newJBuilding);
        _uavr.SaveChanges();

        return Ok();
    }

    [HttpDelete("DeleteSection")]
    public IActionResult DeleteSection(int key)
    {
        var jBuilding = _uavr.Jbuilding.FirstOrDefault(o => o.Id == key);
        // if (jBuilding == null)
        //     return StatusCode(409, "Раздел не найден");

        _uavr.Jbuilding.Remove(jBuilding);
        _uavr.SaveChanges();

        return Ok(key);
    }
