The third parameter to the Ext.Component.on function is an optional scope parameter. If you insert the "this" keyword there, you will maintain scope in your callback function. Should go like this:

afterChartLayout: function(){
    if(this.initializedEvents==true) return;
    this.initializedEvents=true;
    Ext.getCmp('barColumnChart').series.items[0].on('itemmousedown',function(obj){

        alert(obj.storeItem.data['source']+ ' &' + obj.storeItem.data['count']);
        //Call other function on the controller
        this.otherControllerFunction('paramOne');
        //Make sure to include "this" on the next line!!
    }, this);
}
