Extjs get Model by Controller - extjs

Question

I get controller bind to model, and model with proxy on it. I try to get model in controller init function. I use next code:
Ext.define("AM.controller.Main", {
extend: 'Ext.app.Controller',
views: [
'Grid'
],
models:[
'AM.model.Points'
],
init: function(){
var m = this.getModel('AM.model.Points');
m.getCount();
}
But the getCount is not defined. When I print variable m it says it is function: constructor() :
function constructor() {
return this.constructor.apply(this, arguments) || null;
}
What should I do to get right model object of controller?
Here I add my store, my model with proxy on it:
Ext.define('AM.store.ServerStore', {
extend: 'Ext.data.Store',
model: 'AM.model.Points'
});
Ext.define('AM.model.Points', {
extend: 'Ext.data.Model',
idProperty: {
name: 'UUID',
type: String,
isUnique: true
},
fields: [
{
name: 'NO',
type: "string"
},
{
name: 'Y',
type: "int"
},
{
name: 'ROW',
type: 'int'
},
{
name: 'SEAT',
type: 'string'
},
{
name: 'PROCEEDED',
type: 'int'
},
{
name: 'X',
type: "int"
},
{
name: "CurrentPlace",
type: "int",
defaultValue: 0
}
],
proxy: {
type: 'ajax',
url: 'http://localhost:81/is-bin/INTERSHOP.enfinity/WFS/EnterpriseOrg-MainChannel-Site/ru_RU/-/RUR/HallScheme-PrepareHSXML?HallSchemeElementUUID=zm1VFZxy014AAAENz2ZCr4MF',
method: 'POST',
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
params: {
"HallSchemeElementUUID" : "zm1VFZxy014AAAENz2ZCr4MF"
},
remoteSort: true,
reader: {
type: 'xml',
record: 'PLACE'
},
writer: {
type: 'xml',
root: 'PLACE'
}
}
});

Models are used to defined a record structure in a store. The getCount() does not exist for the Model class in ExtJS.
Instead, you need to be referencing your store in your controller that contains your models and call getCount() on the store instance.
E.g.
var store = this.getStore('storeName');
//or
//var store = Ext.getStore('storeID');
var numRecords = store.getCount();
