event in controller

[chandan.behura]

Hi,
I am unable to get the selectionchange event of grid in controller.
Give all my codes.
grid code that is inside a window.

var regionSM = Ext.create('Ext.selection.CheckboxModel');
Ext.define('LLSO.view.deliveryGroupPerformance.summary.SummaryRegionPopUp', {
    extend : 'LLSO.view.components.PopUp',
    alias : 'widget.summaryregionpopup',
    id : 'summaryregionpopup',
    title : 'summaryregionpopup',
    requires : [ 'LLSO.view.components.CheckGrid' ],
    action : 'showRegion',
    initComponent : function() {
        this.items = [
        {
            xtype : 'checkgrid',
            itemId : 'regionCheckgridId',
            id : 'regionCheckgridId',
            store : 'deliveryGroupPerformances.RegionStore',
            selModel : regionSM,
            selType : 'checkboxmodel',
            action : 'change',
            columns : [ {
                menuDisabled : true,
                dataIndex : 'region',
                text : 'All',
                flex : 1
            } ],
            viewConfig : {
                stripeRows : true,
                action : 'regionPrefAction'
                
            }/*,
            listeners :{
                selectionchange : function(){
                    alert(6);
                }
            }*/
        } ];
        this.callParent(arguments);
    },
    layout : {
        type : 'vbox',
        align : 'right'
    }

});

controller

            'checkgrid[action=change]': {
                selectionchange : this.onSelectionChange
                }



    onSelectionChange: function(){
        alert("got change");
    },

But when i am using the listener inside the view it is working.

How i will take the selectionchange event to controller

First issue I see is you are creating an instance of the checkbox selection model outside initComponent. You should move that line to within the initComponent.
