Freezing text controls when I try to modify text from c++

[neda]

Hi,
QML Text controls is freezing for several second when I try to modify text from c++.

My code:

MyXML.h:

    Q_PROPERTY(QString newPROPERTY1 READ getPROPERTY1 WRITE setPROPERTY1 NOTIFY pROPERTY1Changed)
    .
	.
	.
    Q_PROPERTY(QString newPROPERTY18 READ getPROPERTY18 WRITE setPROPERTY18 NOTIFY pROPERTY18Changed)
 
public:
    MyXML();
    MyXML(QString);
    Q_INVOKABLE QString getPROPERTY1() const;
    .
	.
	.
    Q_INVOKABLE QString getPROPERTY18() const;
 
public slots:
