You have to use apex:inputFile instead of the plain html input type="file" tag:

<apex:inputFile value="{!attch.Body}" filename="{!attch.Name}" id="fileattch"/>


In your controller you will have:

public Attachment attch {
    get {
        if (attch == null)
            attch = new Attachment();
            return attachment;
        }
    set;
}
