Dynamic Combobox in Extjs6.5 not working - extjs

Question

I try to create a combobox(with autoCompleted) and a remote store.When a user types some letters in the combobox,it goes to the server to take a new Datastore.
And I get nothing in my combobox.What's wrong with my code?How can I do for this?
Here's my combobox:
Ext.define('HDDTest.view.mod.searchDetails', {
extend: 'Ext.Panel',
controller: 'home',
items: [
{
xtype: 'combobox',
width: 450,
id: 'createRelatedConceptComboBox',
name: 'createRelatedConceptComboBox',
fieldLabel: 'Test',
//hideTrigger:true,
valueField: 'text',
emptyText: 'Select Concept',
typeAhead: true,
typeAheadDelay: 350,
minChars: 1,
listeners: {
change: 'onRelatedConceptComboBoxClicked'
},
store: {
type: 'GetRelatedConceptStore'
}
}
]
});
Here's my controller:
Ext.define('HDDTest.controller.main.HomeController', {
extend: 'Ext.app.ViewController',
alias: 'controller.home',
onRelatedConceptComboBoxClicked: function (constructors, text) {
var getRelatedConceptStore = Ext.create('HDDTest.store.GetRelatedConceptStore');
getRelatedConceptStore.load({
params: {
sValue: 'text'
},
callback: function (records, success) {
},
scope: this
});
}
});
Here's my store:
Ext.define('HDDTest.store.GetRelatedConceptStore', {
extend: 'Ext.data.Store',
field: ['value', 'text'],
alias: 'store.GetRelatedConceptStore',
storeId: 'GetRelatedConceptStore',
autoSync: true,
autoLoad: true,
proxy: {
type: 'ajax',
url: "http://127.0.0.1/api/TSGH/GetAllSearchResults",
method: 'GET',
reader: {
type: 'json',
rootProperty: '',
transform: function (records) {
var data = new Array();
for (var i = 0; i < records.length; i++) {
data[i] = new Array();
data[i][0] = records[i].NCID;
data[i][1] = records[i].DEFAULT_NAME + '(' + records[i].NCID + ')';
}
console.log(data);
return data;
}
}
}
});
When I type some letters in my combobox I get nothing and without any error messages in my console window. How can I do for this?
Thanks in advance, Ben

There seems to be some error in the processing of transform() method or the Model field name for the displayField property.
Here is the working code with transform() method commented out.
