MJoin tables

Hello Alan.
I need your help to connect two tables together using the same generator Id.
For example, one employee has certain generator Id and when he/she starts to create a new row of the table, this row will have the same generator id connect this employee and his rows.
When I want to open this form it should show me only his/her rows that connect to his/her form. The Database will store all rows from employees. I try to figured it for couple weeks already and I am stuck on it. Please give me idea what do I need to use here to resolve this issue.
I tried to use in Controller table "Where" statement but it didn't work.
There are my code for Table js:

(function($){

$(document).ready(function() {
var editor = new $.fn.dataTable.Editor( {
ajax: '/api/Table',
table: '#Table',
fields: [
{
"label": "GeneratorID:",
"name": "generatorid",
"className": "formidne"

        },
        {
            "label": "MATExample#:",
            "name": "mate_example"
        },
        {
            "label": "Description:",
            "name": "description",
            "type": "textarea"
        },
        {
            "label": "Example2",
            "name": "example2"
        },
        {
            "label": "Example3:",
            "name": "example3"
        },
        {
            "label": "Example4",
            "name": "example4"
        }
    ]

});

editor.on('open', function () {

    var id1 = $("#thisid").val();
    var id2 = $("#thisid2").val();
    if (id1 != "") {
        var id = $("#thisid").val();


    }
    else {
        var id = $("#thisid2").val();

    }

    $("#DTE_Field_generatorid").val(id);
    $(".formidne").hide();



});

var table = $('#Table').DataTable({
    columnDefs:[
       {visible:false,targets:0}
    ],
    dom: 'Bfrtip',
    ajax: {
        url: '/api/Table',
        type:"post",
        data: {"generatorid": formId}
         data:function(data){
           data.generatorid = $("#thisid2").val();
            var formId = data.generatorid;


         }

},

    columns: [
        {
            "data": "generatorid"

        },
        {
            "data": "mate_example"
        },
        {
            "data": "description"
        },
        {
            "data": "example2"
        },
        {
            "data": "example3"
        },
        {
            "data": "example4"
        }
    ],

    select: true,
    responsive:true,

    buttons: [
        { extend: 'create', editor: editor },
        { extend: 'edit',   editor: editor },
        { extend: 'remove', editor: editor }
    ]
});

} );

}(jQuery));

Code for Controller:

public class AdjustmentTableController : ApiController
{
private readonly string dbCon = " Example";
[Route("api/Table")]
[HttpGet]
[HttpPost]
public IHttpActionResult Table()
{

        var request = HttpContext.Current.Request;

        using (var db = new Database("sqlserver", dbCon))
        {

            var response = new Editor(db, "Table","generatorid").Where(q => q.Where("generatorid", " ", "="))
                .Model<TableModel>()
                .MJoin(new MJoin("Form").Model<Model>()
                 .Link("Table.generatorid", "Form.generatorid"))
                .Process(request)
                .Data();

            return Json(response);
        }
    }
}

}

Using Mjoin should give me results from both tables but don't working.

Also, have cshtml and model class that they are easy.

Please give me ideas what do I need to use, maybe "LeftJoin " statement I can use. Let me know if you need anythin else.

Thank you very much!!
