EXTJS:过滤器存储不会发生第一次点击组合

Question

我想过滤一个从组合中选择值的商店。当我选择第一个值时它不会过滤它但是在第二次选择任何其他值时它运行良好
我的商店有 autoLoad=true
这是我的代码

        {
            Ext.getCmp('onlinePay-cmbChequeNo').clearValue();
            Ext.getCmp('onlinePay-cmbChequeNo').getStore().removeAll();
            Ext.getCmp('onlinePay-cmbCrAccount').clearValue();
        }
        var store = Ext.getCmp('onlinePay-cmbCrAccount').getStore();
        if(this.getValue()=="Cheque" || this.getValue()=="Internet/Mobile")
        {   
            Ext.getCmp('onlinePay-chkIncCharges').setValue(false);
            if(this.getValue()=="Internet/Mobile")
            {

                Ext.getCmp('onlinePay-chkIncCharges').enable();
            }
            //Filter store on bank accounts
            store.filter([
