title: How to update content in Row after selection in dojo datagrid
body: <p>I have created one dojo datagrid. Every column has a formatter attached to it. When grid is generated the formatter is called. Now I want it so that if a user selects any row the formatter will be called and some strings should be attached to the selected row's column element.</p>
  
  <p>Like grid is like this :</p>
  
  <pre><code>COLUMN
  -------
  a
  
  b
  
  c
  </code></pre>
  
  <p>and now user selects the 2nd row, the grid should change to :</p>
  
  <pre><code>COLUMN
  -------
  a
  
  b SELECTED
  
  c
  </code></pre>
  
  <p>Currently I implemented it like this :</p>
  
  <pre><code>if(this.grid.selection.selectedIndex !== -1){
    retrun value + "SELECTED";
  }else{
   return value;
  }
  </code></pre>
  
  <p>Can you please suggest a some good way of doing this? Please note that "SELECTED" string should not be added to the grid store.</p>
