Hello World

I have a problem with listeners in a store. It will be only "beforeload" fired, every other event will do nothing. I hope someone can help me.

PHP Code:
app.sellersStore = new Ext.data.TreeStore({    model'Seller',
    
proxy: {
        
type'ajax',
        
url'/api/geo/sellers/search.json',
        
reader: {
            
type'tree',
            
root'results'
        
}
    },
    
listeners: {
        
add: function(storerecordsindex) {
            
console.log("add");
        },
        
load: function(storerecordsindex) {
            
console.log("load");
        },
        
clear: function(storerecords) {
            
console.log("clear");
        },
        
beforeload: function(storeopt){
            
console.log("beforeload");
        },
        
datachanged: function(store) {
            
console.log("datachanged");
        }
    }


});
