Asp.net MVC retrieve information from server with Javascript

Question

I'm working on a Asp.net Razor application. I have a table on my page, and have some names of people as the y_axis for this table.

I have incorporated a tool tip (Tooltipster library) for these names. I would like to display information about these people in the tool tip, info such as their telephone number, city and ID.

This information lies in my database Model. I also have a ViewModel, to retrieve the information as well.

I was wondering how I would retrieve the information and place it in the title attribute that the names/y_axis is located (the information must go in the title for the tool tip to function correctly).

My script:

var engName = document.getElementsByClassName("dhx_matrix_scell");

for (var i = 0; i < engName.length; i++) {

    engName[i].className = engName[i].className + " tooltipss";
    engName[i].title = _______________________________
}

ViewModel:

 public class W6ViewModel
{
    public virtual ICollection<W6ENGINEERS> engineers { get; set; }
}

Controller for the index:

viewModel.engineers = db.W6ENGINEERS.OrderBy(w => w.Name).ToList();

What I tried so far, but get errors

var engName = document.getElementsByClassName("dhx_matrix_scell");
var name = engName.innerHTML();

for (var i = 0; i < engName.length; i++) {

    @{
        //get error here since name isn't visible to the Model
        var engineer = Model.engineers.Where(v => v.Name = name);
    }

    engName[i].className = engName[i].className + " tooltipss";
    engName[i].title = engineer.telephone;
}

Thanks for all your help in advance
