utag.view or utag.link should work (assuming that the tag supports both).
That being said, here are some troubleshooting questions for you to work through:
1) Are _any_ tags firing with the utag.view call? If no other tags are firing, are there JS errors being reported by the browser?
2) If other tags are firing ok with the utag.view call, are updated parameter values causing a load rule applied to the desired tag to evaluate to false? In many cases, a tag not firing is caused by the load rule evaluating to false when it is expected to evaluate to true
3) What's the timing of the initial tag fire to the subsequent tag fire? If they are too close in time, there could be potential problems or exclusions.
4) If all else fails, can you post your utag.view code (or a scrubbed example) here for one of our Solutions team to take a look at? Also helpful would be what tag you are trying to fire via the utag.view call.
