    Default Unanswered: How to activate listeners in renderer function in a grid column

    I am using extjs 4 and I have a grid which shows a field name Approval. Here I have showed checkbox that will be checked when the grid is loaded if the value is true. But if the dataIndex value is fault only the checkbox will appear. Now I want that if I click on unchecked checkbox it will do a action using listeners. But I am not being able to do it. Can anyone please help me on this ? My codes are given below :

    text: 'Approval',
    dataIndex: 'approve',
    flex: 1,
    align: 'left',
    renderer: function(value, metaData, record, row, col, store, gridView){
    if(value == true) {
    return '<input type="checkbox" checked="true" />';
    return '<input type = "checkbox" />';
    listeners: {

    approve: function(){

    First, why not use Ext.ux.CheckColumn that comes with the downloaded zip?
