How can a polar molecule pass through polar channels of proteins in the cell membrane?

To transport a polar molecule through the nonpolar cell membrane, a protein with a polar channel is needed to allow it to diffuse. However, if the molecule is polar and the channel is polar, wouldn't the molecule just be attracted to the polar amino acids and "stick" on the inside of it?I may be thinking of this totally incorrectly, so please bear with my ignorance! Thanks in advance :)
