Two inputs same form column taking all the cell width Bootstrap 3 - twitter-bootstrap-3

Question

I'm trying to get hands over Bootstrap 3 and I'm kindof struggling with the new classes for the grid. Previous versions of Bootstrap let you set the width of a input by adding the span-* class so if you wanted to put two inputs on the same form column, adding span-2 and span-10 did the job. I'm trying to do this with bootstrap 3 but I don't get the same result as you can see in this fiddle, I want to set the select and the input on the same col. I want the labels at top of the inputs so adding the inline class to the form don't work.
What I'm missing here?
Cheers and thanks in advance

Most people can't believe how many classes are involved but form-control is always 100% so each one must go inside a col-- class and if you want to put elements on the same row, in this situation, then you'd use a nested row with columns as follows:
<div class="container">
<form role="form">
<div class="row my-row">
<div class="col-sm-4">
<div class="row">
<div class="col-xs-6">
<div class="form-group">
<label>C-Band</label>
<select class="form-control">
<option value="C15+">C15+</option>
<option value="C12-14">C12-14</option>
<option>
</select>
</div>
</div>
<div class="col-xs-6">
<div class="form-group">
<label> </label>
<input type="text" class="form-control">
</div>
</div>
</div>
</div>
<div class="col-sm-2">
<div class="form-group">
<label>C-Band</label>
<select class="form-control">
<option value="C15+">C15+</option>
<option value="C12-14">C12-14</option>
<option>
</select>
</div>
</div>
<div class="col-sm-2">
<div class="form-group">
<label>C-Band</label>
<select class="form-control">
<option value="C15+">C15+</option>
<option value="C12-14">C12-14</option>
<option>
</select>
</div>
</div>
<div class="col-sm-2">
<div class="form-group">
<label>C-Band</label>
<select class="form-control">
<option value="C15+">C15+</option>
<option value="C12-14">C12-14</option>
<option>
</select>
</div>
</div>
<div class="col-sm-2">
<div class="form-group">
<label>C-Band</label>
<select class="form-control">
<option value="C15+">C15+</option>
<option value="C12-14">C12-14</option>
<option>
</select>
</div>
</div>
</div>
</form>
</div>
Because the gutter is too wide for my taste:
.row.my-row, .row.my-row .row {
margin-left:-1%;
margin-right:-1%
}
.row.my-row [class*="col-"] {
padding-left: 1%;
padding-right: 1%;
}
.row.my-row .row [class*="col-"] {
padding-left: 1%;
padding-right: 1%;
}
