title: Wijmo Grid How to get a cell id
body: <p>I'm using the wijmo grid. Within the grid if a user click on a cell I want to know the id field is.</p>
  
  <p>i.e. if the header details was id, name, surname, dob</p>
  
  <p>When they click on surname I need to be able to retrieve the id. Bit of a rubbish example, but I also need to use selectionMode: "singleCell",</p>
  
  <p>So I don't want to select the full row just one cell, but to be able to retrieve the other cell information within that row</p>
  
  <p>Any Ideas?</p>
