title: Performing custom arithmetic operation on Kendo UI Grid Columns
body: <p>This may be very simple for regular users but as a  newbie  i am kind of struggling to perform<br>
  simple arithemetic operation whereby i want to multiply one of the column values i.e. (DealValue) by 0.05. I looked at kendo docs but surprisingly i couldn't find anything relevant. Anyone got any solution for this? if i run this code i get the errror at the template section of the DealValue Column causing the grid not to be displayed.</p>
  
  <p>Here's my Kendo grid column definition</p>
  
  <pre><code>            columns: [

                     width: 150,
                     title: "Issuer",
                     filterable: {
                         operators: {

                                 startswith: "Starts With",
