This is a simple issue but can be a bottleneck when you are starting out…
Set the pageParam in the store to what you use for pagination on the server side… Then everything should work fine…

Note: Your actual pagination logic should be on the server side… Sencha only provides a means to display the content a few at a time…

Ext.define('MyApp.store.MyJsonStore', {
extend: 'Ext.data.Store',

config: {
    storeId: 'MyJsonStore',
    proxy: {
        type: 'ajax',
        pageParam: 'page',//This parameter needs to be modified
        reader: {
            type: 'json'
        }
    }
}

});
