was only interping when partial was injected (in Bootstrap.load...). The effect was that if there NTs in only the body they were not compiled but not interped. Fixed by adding interp to Export. Note: also tested this change for regressions and found none.
error in interping model vars behind selects now fixed. problem was the 'selected' prop was not correctly being applied to the constructed DOM. See diff for explanation.
now listeners on model attribs backing selects have different types: interp change and select change. the latter is basic DOM change event, the former is fired when underlying model is changed.
