I am using kendo grid popup editor with a template.

.Editable(c => { c.TemplateName("_CustomTemplate").Mode(GridEditMode.PopUp); })

This is the _CustomTemplate i am using

@model Models.CustomViewModel
<div id="popupeditor">
    @Html.HiddenFor(model => model.Id)
    <button type="button" id="NewEmailButton">Add New Email</button>
</div>

And the template is using this model.

public class CustomViewModel 
{
    public string Name { get; set; }
    public List<string> EmailList { get; set; } = new List<string>();
}

User can add new input for email by clicking the "Add New Email" button. I am adding the input to PopUp container with javascript.

function AddEmail() 
{
    let index = 0;
    let input = '<input name="EmailList[index]" type="text"/>'
    $(input).appendTo('#popupeditor');
}

The problem is when i add or remove email it doesn't save, it doesn't go to save method. If i edit the Name it goes to the Save method but EmailList does not bind to model, it stays empty.
