I am afraid that I am not able to reproduce the issues you have raised here. I have created a sample to test this issue and it worked fine for me.
Please download the sample from the following location:
autocompletetest.zip Could you please try running the attached sample and if still the problem exists, kindly try reproducing the issues with this sample and send it back to me so that it would help me to find out the cause of the issue.
