Respected Forough Mortazavi Your  measurement model results are perfectly fit. Lower correlations have no relation to model fit. Lowe correlations means there is weak association among the measured factors.

If you want to be more robust in your testing you should model additional constraints like elasticities.

your model have a good fit, eventhogh I will recommend you to check the modification indicies for better fit.

Dear Forough Mortazavi 

Greetings,

Yes , your model fine and perfect , and I agree what other researchers said .

Best Regards
