  Surges have regularly been observed mostly in H$_{\alpha}$ 6563~{\AA} and
Ca~{\sc ii} 8542~{\AA}. However, surge$'$s response to other prominent lines of
the interface-region (Mg~{\sc ii} k 2796.35~{\AA} $\&$ h 2803.52~{\AA}, O~{\sc
iv} 1401.15~{\AA}, Si~{\sc iv} 1402.77~{\AA}) is not well studied. Here, the
evolution and kinematics of six homologous surges are analysed using IRIS and
AIA observations. These surges were observed on 7$^{th}$ July 2014, located
very close to the limb. DEM analysis is performed on these surges where the
co-existence of cool (log T/K = 6.35) and relatively hot (log T/K = 6.95)
components have been found at the base. This demonstrates that the bases of
surges undergo substantial heating. During the emission of these surges in the
above mentioned interface-region lines, being reported here for the first time,
two peaks have been observed in the initial phase of emission, where one peak
is found to be constant while other one as varying, i.e., non-constant
(observed red to blueshifts across the surge evolution) in nature. This
suggests the rotational motion of surge plasma. The heated base and rotating
plasma suggests the occurrence of magnetic reconnection, most likely, as the
trigger for homologous surges. During the emission of these surges, it is found
that despite being optically thick (i.e., R$_{kh}$ < 2.0), central reversal was
not observed for Mg~{\sc ii} k $\&$ h lines. Further, R$_{kh}$ increases with
surge emission in time and it is found to have positive correlation with
Doppler Velocity while negative with Gaussian width.
