Extjs issues with Store

I have an Ext.Data.Store. And i have a function, that need to invoke one time, when store is loaded. Only one time. At first i did this:

function invokeMe() {
alert("!");
}

actionTemplateStore.on('load', function () {
    invokeMe();
}

But one problem isin this solution: I really need once invoce "invokeMe"-function

actionTemplateStore.on('load', function () {
    if (!actionTemplateStore.actionInvoked) {
        invokeMe();
        actionTemplateStore.actionInvoked = true;
    }
}

Update: as Lloyd mentioned, you can also use {single:true} option.

actionTemplateStore.on('load', yourFunction, {single:true});

Try this:

function invokeMe() {
alert("!");
}

actionTemplateStore.on('load',function () {
    invokeMe();
},this,{single: true});

We pass in this for the scope and a config object with single: true which causes it to execute only once.

You could also do this:

var onLoad = function(store) {
    alert('!');
    store.un('load',onLoad);
}

actionTemplateStore.on('load',onLoad);
