title: Button click does not work in Celltemplate angular grid
body: <p>I m trying to work with celltemplate. But click event did not work.</p>
  
  <pre><code>    $scope.format = function(val){
              return val.replace(/\//g, "");
          };
  
          var executionColumns = {
              data: [],
              enableSorting: true,
              paginationPageSizes: [25, 50, 75],
              paginationPageSize: 25,
              enableColumnMenu: true,
              enableFiltering: true,
              columnDefs: [
  
                { field: 'StartDate', cellTemplate: '&lt;button ng-click="format (row.entity)"&gt;log&lt;/button&gt;' },
                { field: 'Status' },
  
              ]
  
          };
  </code></pre>
