Good day, i´m using version 3.x of extjs, and i like to know if i can add button to tbar and handle a date comparision?, in the version I have published there is already a column filters with the date comparision as you see in the image . but the need is to launch the same filter from the top bar

the current console log for the selected options are

filter2.png

the code to correspont that is

Code:
RestultGrid.filters =  new Ext.ux.grid.GridFilters({filters:
    [
            {type: 'date',    dataIndex: 'fecha_generacion'},
            {type: 'string',  dataIndex: 'other filters .... etc'},


            ]
    });
    
RestultGrid.grid = new Ext.grid.GridPanel({
    width:960,
    height:640,
    store: RestultGrid.store,
    plugins:RestultGrid.filters,
    trackMouseOver:false,
    disableSelection:true,
    loadMask: true,
    columns:[
        {
            // all the other columns etc....
        }
        ,{
            id: 'fecha_generacion',
            header: "Fecha Generación",
            dataIndex: 'fecha_generacion',
            align: 'left',
            width: 140,
            sortable: true
        }
        
    ],
    viewConfig: {
        forceFit:true
    },
    tbar  : [
        {
            text:'Filter by Date',
            iconCls: 'icon-refresh',
            handler : function(){
                // call here the datepicker
            }
        }]
});
Many Thanks in advance
