(Testsystem: Windows 7, Mathematica 10.3.1.0, Firefox 24.0) Try the following:
gui[] := DynamicModule[
{a, b, c, d},
Row[{
Column[{
Slider[Dynamic[a], {0, 2}],
Slider[Dynamic[b], {0.1, 2.1}],
Slider[Dynamic[c], {0, 2.1*Pi}],
Slider[Dynamic[d], {0, 2*Pi}]
}],
Dynamic[
Plot[a * t + b * t^2 + c * t^(-2) + d * t^(-1), {t, 0, 10},
PlotRange -> {{0, 10}, {-10, 10}}]]
}]
]
CloudConnect[]
CloudDeploy[gui[]]
And check out the result in a web browser - and wonder... ...why just the movement of the last dynamic slider (the one connected to variable d) leads to an update of the belonging dynamic plot. It seems that just the product of an integer with a constant alike Pi in the slider's range is able to accomplish a proper updating behaviour of the slider/plot!?
(Note that the behaviour in a Mathematica Notebook differs from said behaviour in a webbrowser)
Any idea why? Any idea how to improve the situation in a webbrowser/cloud without corrupting the (relatively proper) behaviour in a notebook?

PS: By the way, it is not helpful, that the post preview differs significantly from my input - e.g. an 'at' is transformed to an 'at' - which is definitely not the same (without a space in between!!) - so I had to insert some spaces around the '' manually...
